What is the difference between biodiesel and bioalcohol oil

To be honest, it is alcohol-based fuel, I am doing physical delivery every day, restaurants, factory boilers can also be done, stronger than going to work, I want to know about one three five, six two long, one bar three two zero, you can first understand the market raw materials, etc.

Biodiesel refers to the monoalkyl ester of fatty acids obtained by transesterification of animal and vegetable oils and fats (fatty acid triglycerides) and alcohols (methanol or ethanol), the most typical is fatty acid methyl esters. The chemical composition of the two is different. Biodiesel does not contain hydrocarbons and is composed of esters, whereas diesel contains only hydrocarbons.

Biodiesel is obtained by extracting plant seeds containing oils and fats, and diesel is obtained by extracting underground petroleum resources.

In terms of viscosity, the viscosity of biodiesel and diesel that meet the national standard is comparable; In terms of anti-knock performance, biodiesel is better than diesel; In terms of calorific value, biodiesel is slightly lower than diesel. Under normal circumstances, biodiesel is not used alone for automobiles, and foreign countries currently use 5%-20% biodiesel to add 5%-20% to diesel, and its power performance is basically equivalent to petrochemical diesel, if the proportion is too large, its power will be lower than that of petrochemical diesel.

Biodiesel is a mixture of complex organic components with extremely high oxygen content, which are mainly organic compounds with large molecular weight, including almost all kinds of oxygenated organic compounds, such as: ethers, esters, aldehydes, ketones, phenols, organic acids, alcohols, etc. It is a kind of biomass energy, and it is a monoalkyl ester of a long-chain fatty acid obtained by biomass using pyrolysis and other technologies.

Hello, I am the life of the answer to the little flower, I am happy to answer for you. The difference between bio-heavy fuel oil and biodiesel is mainly different in composition, nature and use. Bio-heavy fuel oil and biodiesel are both fuels that are derived from biomass, but they differ slightly in composition, properties and uses.

1.Bio-heavy oil is a kind of liquid fuel similar to petroleum heavy oil obtained by biomass through thermal cracking, gasification, liquefaction and other processes, its main components are hydrocarbons and impurities, with high viscosity, high density, high calorific value, suitable for use in industry and ships and other large-scale equipment fuel. 2.

Biodiesel is a liquid fuel prepared from biomass through chemical reactions such as esterification or hydrogenation of the burier, and its main components are ester compounds such as methyl ester or ethyl ester, which has the characteristics of low viscosity, low density, high oxygen content and low emission pollutants, and is suitable for use in the stuffy material of road traffic. 3.Therefore, there are great differences in the composition, properties and uses of bioheavy fuel oil and biodiesel.

The above is my answer, I hope it helps, thank you!

Both bio-heavy fuel oil and biodiesel are fuels converted from biomass, but there are some differences between the two. 1.The ingredients are different.

Bio-heavy oil mainly refers to oily fuels from agricultural and forestry wastes, and its main components are carbohydrates such as lignin and hemicellulose; Biodiesel, on the other hand, is obtained by esterification of vegetable oils and fats, and its main component is triglycerides. 2.The energy density is different.

Bio-heavy oil has a higher density and a lower energy density, so its specific calorific value is also low. Biodiesel, on the other hand, is usually higher in average specific calorific value than bio-heavy oil because it is mainly composed of grease. 3.The field of application is different.

Due to the low specific calorific value of bio-heavy oil, it is mainly used as a fuel for the production of electricity and heating equipment; Biodiesel, on the other hand, is mainly used in transportation and mechanical power mining applications, such as automobiles, trucks, airplanes, etc. 4.The environmental performance is different.

Biodiesel is more environmentally friendly than bio-heavy oil, because the exhaust gas emitted by biodiesel during combustion contains much less environmental pollutants than bio-heavy oil, such as SOX, NOX, etc. In general, biodiesel has better performance and a wider range of applications than bio-heavy oil, but bio-heavy oil still has its needs and applications in specific fields.

Bio-heavy oil tung dong and biodiesel are two different fuel types. The main differences between them are the production process, raw materials and uses. 1.

Production process: The production process of bio-heavy oil usually uses organic wastes such as biomass or waste oil as raw materials, and uses heating, pressing, deodorization and other processes for extraction and refining. The production process of biodiesel requires vegetable oil or animal oil to be processed by chemical reactions such as esterification and methanolation.

2.Raw materials**: The raw materials of bio-heavy oil usually include waste oil, animal oil, biomass and other organic wastes, while biodiesel is mainly used in vegetable oil, animal oil and other natural oils.

3.Characteristics and uses: Bio-heavy oil has the characteristics of high calorific value, low sulfur and low volatility, and is mainly used in industrial power generation, hot water ** and other fields.

Biodiesel, on the other hand, has the advantages of easy use, high combustion efficiency, and reduced greenhouse gas emissions, and is mainly used in transportation, agricultural machinery and other fields. It should be noted that although bio-heavy oil and biodiesel are both biomass fuels, their production and use also face some technical and economic constraints, such as high production costs, collection, storage and other problems, so it is necessary to further strengthen research and application in the process of practical application.

Summary. Both bioheavy fuel oil and biodiesel are products of biomass energy, but their uses and properties differ. Bio-heavy oil is a liquid fuel similar to traditional petroleum heavy oil, which is mainly used as a fuel for large industrial equipment such as power plants and industrial boilers.

It is usually produced through technologies such as biomass pyrolysis, gasification, etc., and bio-heavy oil has a lower carbon footprint compared to traditional petroleum heavy oil. Biodiesel is a fuel that can directly replace traditional petroleum diesel, mainly used as a fuel for diesel engines. It is usually obtained by converting biomass into bio-oil and then esterifying or hydrotreating it.

Biodiesel also has a lower carbon footprint compared to traditional petroleum diesel. Overall, bio-heavy fuel oil and biodiesel are both types of renewable energy sources that have a lower environmental impact and are more sustainable in their production processes. However, their application scenarios and production technologies are different, and they need to be selected according to the specific situation.

Their purpose and nature are different.

Can you add, I don't quite understand it.

Both bioheavy fuel oil and biodiesel are products of biomass energy, but their uses and properties differ. Bio-heavy oil is a liquid fuel similar to traditional petroleum heavy oil, which is mainly used as a fuel for large industrial equipment such as power plants and industrial boilers. It is usually produced through technologies such as biomass pyrolysis, gas-fired and potatochemical, and bio-heavy oil has a lower carbon footprint compared to traditional petroleum heavy oil.

Biodiesel is a fuel that can directly replace traditional petroleum diesel, mainly used as a fuel for diesel engines. It is usually obtained by converting biomass into bio-oil at an early loss, and then esterification or hydrotreating it. Biodiesel also has a lower carbon footprint compared to traditional petroleum diesel.

Overall, bio-heavy fuel oil and biodiesel are both types of renewable energy sources that have a lower environmental impact and are more sustainable in their production processes. However, their application scenarios and production technologies are different, and they need to be selected and used by the root barker according to the specific situation.

1. Biodiesel refers to the fatty acid methyl ester or ethyl ester formed by the conversion of vegetable oil, animal oil, waste oil or microbial oil with methanol or ethanol.

2. Diesel is a light petroleum product and a complex hydrocarbon mixture. Diesel fuel. It is mainly composed of diesel fraction and mega bridge produced by ** distillation, hydrocracking, stone group chaotic oil coking and other processes.

Biodiesel is not the same as diesel, biodiesel is a combination of biomass energy and traditional fossil energy, which can be partially renewable. Diesel, on the other hand, is a fossil energy source that cannot be renewable, and there will always be a time when it runs out. Biodiesel refers to vegetable oil (such as rapeseed oil, soybean oil, peanut oil, corn oil, cottonseed oil, etc.), animal oil (such as fish oil, lard, butter, sheep fat, etc.), waste oil or microbial oil and methanol or ethanol ester to form fatty acid methyl ester or ethyl ester.

Biodiesel is a typical "green energy", with good environmental performance, good engine starting performance, good fuel performance, wide range of raw materials, renewable and other characteristics. Vigorously developing biodiesel is of great strategic significance for sustainable economic development, promoting energy substitution, reducing environmental pressure, and controlling urban air pollution.
