Biodiesel refers to a renewable diesel fuel that can replace petrochemical diesel oil by transesterification with aquatic vegetable oil such as oil crops, wild oil plants and engineering microalgae, as well as animal oil and kitchen waste oil. Biodiesel is a kind of biomass energy, which is a long-chain fatty acid monoalkyl ester obtained by biomass pyrolysis and other technologies. Biodiesel is a mixture of complex organic components with extremely high oxygen content. These mixtures are mainly some high molecular weight organic compounds, including almost all kinds of oxygen-containing organic compounds, such as ethers, esters, aldehydes, ketones, phenols, organic acids, alcohols and so on. Biodiesel is a kind of high-quality clean diesel oil, which can be extracted from various biomass and can be said to be an inexhaustible energy source. It is expected to replace oil as an alternative fuel in today's increasingly exhausted resources.
Features:
1) has a high water content, up to 30%-45%. Moisture is beneficial to reduce the viscosity of oil and improve the stability of oil, but it reduces the calorific value of oil;
2) 2) The pH value is low, so the storage device is preferably made of acid-resistant materials;
3) The density is higher than that of water, and the ratio to water is about1.2;
4) There is a tendency of "aging", heating should not exceed 80℃, and light and air should be avoided;
5) Good lubrication performance.
6) Excellent environmental protection characteristics: low sulfur content, low emission of sulfur dioxide and sulfide, the biodegradability of biodiesel is as high as 98%, and the degradation rate is twice that of ordinary diesel, which can greatly reduce the environmental pollution caused by accidental leakage;
7) Good low-temperature engine starting performance;
8) Good safety performance: high flash point and safe transportation, storage and use;
