Is gas CH4 or CO

**。The combustion gas sources in people's lives are roughly divided into three categories: liquefied petroleum gas (Y), artificial gas (R), and natural gas (T).

Liquefied petroleum gas (referred to as liquefied gas) 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, which should be used with great attention.

Natural gas is a broad term for naturally occurring gases buried in formations. However, the so-called natural gas usually refers to a hydrocarbon-rich combustible gas stored in the deeper part of the formation, while natural gas that coexists with oil is often called oilfield associated gas. Natural gas is converted from organic matter hundreds of millions of years ago, and the main component is methane, in addition, according to different geological formation conditions, it also contains different amounts of low-carbon alkanes such as ethane, propane, butane, pentane, hexane, and non-hydrocarbon substances such as carbon dioxide, nitrogen, hydrogen, sulfides, etc.; Some gas fields also contain helium.

Natural gas is an important energy source that is widely used as city gas and industrial fuel; In the 70s, natural gas accounted for about 18 19 of the world's energy consumption. Natural gas is also an important chemical raw material.

The calorific value of natural gas combustion per cubic meter is 8000 kcal to 8500 kcal.

The calorific value of combustion per kilogram of liquefied gas is 11,000 kcal. The specific gravity of gaseous liquefied gas is kilogram cubic meters. The calorific value of combustion per cubic meter of liquefied gas is 25,200 kcal.

In this way, it can be seen that the calorific value of one cubic meter of liquefied gas is three times that of natural gas, but there are reports that the calorific value of liquefied gas is seven times that of natural gas.

Each bottle of liquefied gas weighs kilograms, with a total calorific value of 159,500 kcal, which is equivalent to the calorific value of 20 cubic meters of natural gas.

1. The main components of coal gas are carbon monoxide and hydrogen, and the main components of liquefied gas are organic compounds such as propane and butane, including CH4, which are not only flammable, explosive but also toxic.

2. Coal gas is a gas containing combustible components processed from coal as raw material. 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).

3. The calorific value of these gases is low, so they are also collectively referred to as low calorific value gasThe gas obtained by coking in the coal dry distillation method is called coke oven gas. It belongs to the medium calorific value of gas, which can be used as a civil fuel in the city. Carbon monoxide and hydrogen in coal gas are important chemical raw materials.

1. CO: The chemical name is carbon monoxide, highly toxic!After carbon monoxide enters the human body, it will combine with hemoglobin in the blood to produce carboxyhemoglobin, which in turn makes hemoglobin unable to combine with oxygen, thus causing hypoxia in body tissues, resulting in suffocation and death in the human body, so carbon monoxide is toxic.

Carbon monoxide is a colorless, odorless and tasteless gas, so it is easy to ignore and cause poisoning.

2. CH4: The chemical name is methane, biogas, natural gas, gas gas, and the main components are methane, which is flammable and explosiveAt the molecular level, methane is a more active greenhouse gas than carbon dioxide, but it is found in smaller quantities in the atmosphere.

It is widely found in natural gas, biogas, coal mine pit gas, is a high-quality gaseous fuel, and is also an important raw material for the manufacture of syngas and many chemical products.

At present, the main ingredient of household bottled gas is liquefied petroleum gas, which is an alkane containing three to five carbon atoms.

The main components of pipeline gas vary from city to city, some are methane (CH4), and some are alkanes containing three to five carbon atoms.

Blast furnace gas: contains carbon dioxide, carbon monoxide.

Coke oven gas;Carbon monoxide.

Pyrolysis gas: petroleum gas such as ethylene.

Water and gas;Hydrogen and carbon monoxide.

The composition of coal gas is CO, and the main component of natural gas is CH4

Hello water gas is: water (H2O) and coke (C) react under specific conditions of high temperature to produce a mixture of hydrogen (H2) and carbon monoxide (Co), the main components of water gas are H2 and CO.

CH4 is methane, and it is also the main component of natural gas and biogas

GH Gas has the answer for you:

1. C capitalization o capitalization is CO, is the molecular formula of carbon monoxide, under normal conditions, carbon monoxide is colorless, odorless, tasteless, toxic gas, insoluble in water, melting point -199, boiling point. The density of the gas under standard conditions is very small from the density of air under standard conditions, which is also one of the factors that make it easy to get gas poisoning. It is a neutral gas.

2. Natural gas (narrow sense) is a mixture, which mainly contains methane (molecular formula: CH4), the letters are capitalized, and the numbers are subscripts.

3. If C is uppercase o is lowercase, that is, CO, then it is the element symbol of the metal "cobalt".
