The differences and connections between biodiesel and biofuel oil. Thanks!

Biodiesel

(Biodiesel) refers to aquatic plant oils such as oil crops, wild oil plants and engineered microalgae, as well as animal oils, catering waste oil, etc. as raw material oil through transesterification Renewable diesel fuel made by technology that can replace petrochemical diesel. Biodiesel is a type of biomass energy. It is a monoalkyl ester of long-chain fatty acids obtained by thermal cracking of biomass. Biodiesel is a mixture of complex organic components with extremely high oxygen content. These mixtures are mainly organic compounds with large molecular weights, including almost all types of oxygen-containing organic compounds, such as ethers, aldehydes, ketones, phenols, organic acids, alcohols, etc. Compound biodiesel is made from waste animal and vegetable oils, waste engine oil and refinery by-products, and then added with catalysts, and is synthesized through special equipment and special processes.

Definition

Biodiesel [1] refers to fatty acid monoalkyl esters obtained by transesterification of animal and vegetable oils (fatty acid triglycerides) and alcohol (methanol or ethanol) , the most typical one is fatty acid methyl ester. Compared with traditional petrochemical energy, it has low sulfur and aromatic content, high flash point, high cetane number, and good lubricity, and can be partially added to petrochemical diesel.

Raw materials

80% of EU biodiesel raw materials are canola oil (low glucosinolates, low erucic acid). The United States and Brazil mainly use soybeans, while my country mainly uses woody oils, waste oils and microalgae oils as raw materials. my country has launched a microalgae carbon-fixing bioenergy demonstration project in Inner Mongolia. At the same time, it has launched a biodiesel industrialization demonstration project in Sichuan, Guizhou, and Hainan.

Biofuel

(biofuel) generally refers to solid, liquid or gaseous fuels composed or extracted from biomass. It can replace gasoline and diesel produced from petroleum and is an important direction for the development and utilization of renewable energy. The so-called biomass refers to various organisms produced through photosynthesis using the atmosphere, water, land, etc., that is, all living organic matter that can grow. It includes, animals and microorganisms. Different from traditional fuels such as oil, coal, and nuclear energy, this emerging fuel is renewable fuel.

Biofuels generally refer to solid, liquid or gaseous fuels composed or transformed by living organisms. It is an important direction for the development and utilization of renewable energy. It has good storability and transportability and can provide liquid fuel that can replace petroleum. Biofuels in the narrow sense only refer to liquid biofuels, which mainly include fuel ethanol, biodiesel and aviation biofuels.
