What is biodiesel refining
BD100 Biodiesel: 100% pure biodiesel called BD100.B5 bio diesel: 2%~5% (volume fraction) biodiesel (BD100) and 95%~98% (volume fraction) of diesel oil blend fuel, suitable for GB252 or GB19147 suitable for compression ignition engineBiodiesel is a prominent component of environmental performance: the content of oxygen in 11-14% combustion more completely in the car use can not see the exhaust smoke; below 5/100000 sulfur, basically no sulfur dioxide pollution; exhaust hydrocarbons, carbon monoxide discharged more than 50% less than diesel oil; no aromatic compounds, non-toxic, easy degradation. So biodiesel can completely replace petroleum diesel fuel green international fuel market recognized.It is of great strategic significance for the sustainable development of China's economy, the promotion of energy substitution, the reduction of environmental pressure and the control of urban air pollution
In 1983 Quick named it biodiesel (Biodiesel) its chemical structure: RCOOCH3.Made by China Petroleum Chemical Co, Research Institute of petroleum and chemical industry in May 2007 the National Standardization Committee announced and recommended implementation of the "diesel fuel with biodiesel blend (BD100) standard" (GB-T 20828-2007) clearly states: bio diesel, biodiesel, is composed of animal and vegetable oil and alcohol (such as methanol or ethanol) by transesterification of alkyl fatty acid ester was prepared, the most typical is the fatty acid methyl ester, BD100 said.
Biodiesel is also called fatty acid methyl ester, with animal and vegetable oils (soybean and rapeseed oil crops such as palm oil, and other oil tree fruit, Pistacia chinensis oil engineering microalgae aquatic plant oils and animal fats, waste food oil) as raw materials, and low carbon alcohols (methanol or ethanol) by esterification and alcoholysis reaction, long chain fatty acid methyl ester is obtained, a method for internal combustion engine using fuel.
Biodiesel is a kind of biomass energy, biomass energy biomass energy is in existence, green plants through photosynthesis to convert solar energy into chemical energy stored in biomass and internal energy, is a renewable energy. Biomass is the fourth largest energy after coal, oil and natural gas. In addition to the direct combustion of biomass energy utilization of the traditional also, including the use of biological or chemical approach to convert biomass into a gas or liquid products. Biodiesel is the conversion of biomass to liquid fuels.
