What is the product of coal gasification, what is coal gas, and what can gas do?

Coal gasification can obtain syngas, and the downstream products of syngas mainly include synthetic ammonia and methanol, acetic anhydride, dimethyl ether, ethylene, ethylene, propylene, acrylic acid, acrylonitrile, formaldehyde and other basic chemical raw materials. Syngas chemical products are characterized by oxygen-containing organic compounds (oxycarbons), of which the most readily available product is methanol dimethyl ether, which is further derived into aldehydes, ethers, acids and esters, and alcohol ether dehydration can obtain oxygen-free olefins, and further hydrogenation to obtain alkanes.

Syngas chemistry can be broadly divided into four categories: (1) based on CO (formic acid, acetic acid, acetic anhydride, oxalic acid, DMF, vinyl acetate, etc.); (2) Hydrogen-based (synthetic ammonia, urea, urea resin, fuel cells, etc.); (3) Based on carbon dioxide (carbonate solvents, urea, urea aldehyde resin, etc.); (4) Based on CO+ hydrogen (methanol, dimethyl ether, ethylene glycol, ethylene, propylene, acrylic acid, acrylonitrile, polypropylene, polyethylene, formaldehyde and its series, etc.).

Gas coal is a kind of bituminous coal with a low degree of coalification, which is not cohesive or slightly cohesive. No coking in lamellar coke ovens. The flame is short when burned and burn-resistant. Isolated from no air heating, a large amount of gas can be generated. Some gas coal can also be used for oil refining and extracting chemical raw materials. [2]

As the largest gas coal in coking coal, most of them have the characteristics of low ash and low sulfur, and coal blending coking can significantly reduce the harmful components of coke such as ash and sulfur, and reduce coking at the same time.

Pollutant emissions, alleviating the impact of metallurgical production on the atmospheric environment, is the most potential coking coal. [3]

In coal blending and coking, fertile coal has the strongest ability to tolerate gas coal, and the ratio of gas to coal should be controlled based on fertile coal. With the increase of gas-coal ratio, the porosity parameters of coke change significantly, and the thermal properties of coke gradually deteriorate and there are sharp deterioration points, and the influence of gas-coal coking on the thermal properties of coke is mainly achieved by changing the stomatal structure.

The properties and uses of coal gasification are divided into: water gas, semi-water gas, and air gas (or furnace gas) are obtained by coal gasification, and these gases have low calorific value, so they are also collectively referred to as low calorific value gas; Dry coal.

Therefore, the use of gas is still very large, generally speaking, gas and natural gas resources basically belong to the kind of heating and fuel, but gas is generally used now relatively few round drafts, so most of the pre-cavity judgments are based on natural gas.

Coal gas is a gas containing flammable components that is processed from coal. There are many types of gas and its composition is also very complex, and it can generally be divided into two categories: natural gas and artificial gas. Coal gas can be used as a fuel, or as a raw material for ammonia synthesis, petroleum synthesis, organic synthesis, hydrogen production, etc.

Coal gas is produced by chemical reaction from the factory with coal as the main raw material, and its main components are carbon monoxide, hydrogen and methane. Natural gas is mostly derived from natural oilfield gas, which is converted from organic matter hundreds of millions of years ago, and the main component is methane. The calorific value of natural gas is much higher than that of coal gas (that is, the heat released during combustion is much higher than that of coal gas), natural gas has high purity, 95% of the composition is methane, the combustion is complete, it does not contain toxic and harmful impurities such as carbon monoxide and sulfide, and there is no pungent odor, which is a relatively safe gas.

Coal gas is divided into natural gas and artificial gas. Carbon monoxide and hydrogen in natural gas are the chemical raw materials for heavy mining. The main components of artificial gas are combustible gases such as alkanes, olefins, aromatics, carbon monoxide and hydrogen, and contain small amounts of non-combustible gases such as carbon dioxide and nitrogen.

Coal gas is a gas containing flammable components prepared from coal as the original substance or envy material. According to the processing method, gas quality and use, it is divided into: water gas, semi-water gas, air gas (or furnace gas) obtained by coal gasification, these gas mass bi has a low calorific value, so it is also collectively referred to as low calorific value gas; Dry coal.

Natural gas refers to all gases that exist naturally in nature, including gases formed by various natural processes in the atmosphere, hydrosphere, and lithosphere (including Kuanxiao oilfield gas, gas field gas, mud volcanic gas, coalbed methane, and biogenerated gas, etc.).

The long-term common definition of "natural gas" is a narrow definition from the perspective of energy, which refers to a mixture of hydrocarbon and non-hydrocarbon gases naturally contained in the formation. In petroleum geology, it usually refers to oilfield gas and gas field gas. Its composition is dominated by hydrocarbons and contains non-hydrocarbon gases.

Questions. Yes. Hello. 1.

Carbon monoxide is gas, gas is colorless and odorless, the gas can be used to cook rice and boil water, the gas can be used for heating, and the use of gas should pay attention to safety.

Canned liquefied gas is also called gas in general, and the use of gas can be used for cooking, boiling water, and heating food.

Gas is the main energy source we use in our daily lives.

Rationality is a pigment, can you cook and stir-fry without gas? There are a lot of people in the fan shop who have filled 1000 pieces of Meng Meiqi with gas canisters, well, use it to stir-fry the dishes and cook the limbs to make the cherry blossoms, and use it for ignition.

Coal gas is a gas containing flammable components that is processed from coal. According to the processing method, the nature and use of the gas, it is divided into: water gas, semi-water gas, and air gas (or furnace gas) obtained by coal gasification.

Liquefied gas generally refers to liquefied petroleum gas, which is a colorless volatile liquid obtained by pressurized cooling liquefaction of natural gas or oil in an oil refinery. It is very susceptible to spontaneous combustion, and when its content in the air reaches a certain concentration range, it can meet an open flame.

Coal gas or gas is a general term for gaseous fuel, which can be burned and released heat. There are many types of gas, and the main ones used by residents and industrial enterprises are natural gas, artificial gas, and liquefied petroleum gas.

1. Liquefied petroleum gas (y).

It is mainly a by-product of the process of extracting and refining petroleum, and the main components are C3H8 and C4H10

It is divided into three categories: 19y, 20y, 22y, and the rated pressure is 2800pa; The bottled liquefied gas is 20yThe Zheng Qiao or products produced by Wanhe are mainly 20y

2. Natural gas (t).

The main component is CH4, and there are a small amount of unsaturated hydrocarbon broad hidden compounds and CO2, N2, O2, etc.

It is divided into five categories: 4t, 6t, 10t, 12t, 13t

The rated pressure of 10t, 12t and 13t is 2000pa, and the rated pressure of 4t and 6t is 1000pa;

The products produced by Wanhe are mainly 12t and 13tAt present, 13t has basically not been produced, and the so-called natural gas currently mainly refers to 12t products.

3. Artificial gas (R).

There are two main preparation methods:

One is to put its raw coal or coke into an industrial furnace for combustion, and introduce air and water vapor to produce combustible gas;

Or isolate the air to heat, so that the coal undergoes physical and chemical changes, and after heating, the combustible gas can also be purified to obtain tar, ammonia, crude benzene and other chemical products.

Main ingredients: H2; co；ch4；c2；n2；co2.

It is divided into three categories: 5R, 6R, 7R, and the rated pressure is 1000Pa

First of all, the ingredients of the two are not the same. The main components of coal gas are carbon monoxide, hydrogen, and methane. The main components of liquefied gas are propane, propylene, butane, butylene, and a small amount of pentane, pentene and trace sulfur compound impurities.

Gas can only be used where there is a gas plant, where gas pipes have been laid. Liquefied gas can be used wherever there is no gas plant and where there are no gas pipes. Coal gas is a gas containing flammable components that is processed from coal.

Liquefied petroleum gas (LPG) is one of the petroleum products.

The liquefied gas tank is a double-layer tank with stainless steel on the inside, carbon steel on the outside, and a vacuum sandwich in the middle. The gas tank is just ordinary carbon steel, single layer. To know the difference between them, it is best to understand their nature first.

LNG is a liquid state, the temperature is -162, and the pressure is generally 3 kg, so the most important thing is to keep warm, you need a double-layer vacuum tank. The gas is gaseous, at room temperature, and the pressure is 16 kg.

Household liquefied gas generally refers to liquefied petroleum gas (referred to as liquefied gas), which is a kind of petroleum tail gas left in the process of refining gasoline, kerosene, diesel, heavy oil and other oil products. Its main components are ethylene, ethane, propylene, propane and butane, etc., which are liquid in the gas cylinder, and once they flow out, they will vaporize into combustible gas about 250 times larger than the original volume, and are very easy to diffuse, and will burn or ** when encountering an open flame. Therefore, special attention should also be paid to the use of liquefied gas.

Coal gas is prepared from solid raw materials such as coal or coke through dry distillation or vaporization, and its main components are carbon monoxide, methane and hydrogen. Therefore, the gas is toxic and easy for the air to form a ** mixture, and it should also be used with great attention. The main components of coal gas are CO, hydrogen, alkanes, olefins, aromatics, etc.

The gas is toxic because the CO and aromatic hydrocarbons in it can combine with the hemoglobin in the human body, causing hypoxia, making people unconscious or even dying, and at low concentrations, it can also make people dizzy, nauseous and prostrate.

Liquefied gas is mainly used as a petrochemical raw material and can be used as an industrial, civil and internal combustion engine fuel.

The material composition is different, and the main components of liquefied gas are butylene, propylene, and butane.

And propane, the main component of natural gas is alkanes, different types, liquefied gas is divided into coal gas liquefied gas, petroleum liquefied gas.

and natural gas liquefied gas.

The pressure is different, the pressure of liquefied gas is greater than 2800 Pa, the pressure of natural gas is 2000 Pa, the combustion temperature is different, and the flame of liquefied gas is higher than that of natural gas.

Summary. A kind of coal used for distillation to produce gas, generally sintered bituminous gas coal is a kind of bituminous coal with a low degree of coalification, which is not cohesive or slightly cohesive. No coking in lamellar coke ovens.

The flame is short when burned and burn-resistant. Heating in isolation from air can produce a large amount of gas. Some gas coal can also be used for oil refining and extracting chemical raw materials.

A kind of coal used for distillation of tung cavity method to produce gas, generally sintered bituminous gas coal is a kind of bituminous coal with a low degree of coalification, and it is not bonded to reed shirt or slightly cohesive. No coking in lamellar coke ovens. When burning, the flame wheel is short and burn-resistant.

Heating in isolation from air can produce a large amount of gas. Some gas coal can also be used for oil refining and extracting chemical raw materials.

What is the strength of coal.

The main coking coal, the volatile content is between how much.

How much is the volatile content of the coal.

Okay, kiss, wait a minute.

Gas coal is the lowest coking coal with the lowest degree of coalization, with more than 30% of dust, dry and ash-free volatile content, and the maximum thickness of the colloidal layer is greater than 5-25mm. It is mainly used for coking, and is also used as thermal coal and gasification coal. The coal quality is low ash and low sulfur, and the selectivity is good, and it is the one with the largest reserves of coking coal in China.

How much is the volatile content of fertile coal.

The main coking coal is divided according to the national standard, the volatile skin is 18-28 1 3, the volatile content is 32-36, the g value of the main coking coal is in a mess, and the g value is between 65-75, the y value is 15, 1 3, and the g value is between 60-70.

Lean coal is a kind of bituminous coal, which is the name of bituminous coal with high degree of coalification, and is a coking coal with medium cohesiveness with low volatile composition. The dry ash-free base of lean coal has a volatile matter of VDAF > 10% 20%, and the bond index g>20 65. It has less volatiles, weak cohesion, and can coke alone, which is a coking coal.

A certain amount of colloids can be produced during coking. Single coal coking, the coke generated, has poor meltability, small wear resistance, easy to crush, but large lump. It is often used in coal blending coking as a thinning agent, in coking coal, lean coal can play a role in skeleton and easing shrinkage stress, thereby increasing the lumpiness of coke, and is an important component in the coal, so as to improve the lumpiness of coke and reduce the cracks of coke and coke.

It is also used as a raw material for gasification, or as a fuel.

Fertile coal is a kind of bituminous coal, the degree of coalification is higher than that of the ridge, and it is a strong cohesive coal with medium volatile content and high volatile old beam content in the middle cherry tree, and its volatile content is about 25%-35%.

The higher the g value, the better it is for coal.

Yes dear. The thicker the colloids produced by the coal, the better the coking performance in general.

Shanxi low-stream main Jiao Yi what is today**.

In Shanxi, the low-sulfur Bishen main coking coal is 300-650 yuan, the low-sulfur lean coal is 300-530 yuan, and the high-sulfur lean coal is 200-300 yuan.
