Abstract

The invention discloses a biodiesel and a preparation method thereof, and belongs to the technical field of biodiesels. A solid acid catalyst is adopted to catalyze a reaction of biomass oil and low carbon alcohol to produce fatty acid methyl ester, and the obtained product and the catalyst can be easily separated, so the emission of a large amount of waste acid and waste alkali is avoided, and the pollution to environment is effectively prevented. The biodiesel product has the advantages of good cold filter plugging effect, no cold filter plugging point reversion problem, efficient stable dispersion capability, good oil solubility, enhancement of the filter screen pass-through property of diesel oil, and improved CFPP (cold filter plugging point) performance. The preparation method of the biodiesel has the advantages of simplicity, wide raw material source, economy and feasibility.

Description

technical field [0001] The invention relates to biodiesel and a preparation method thereof, belonging to the technical field of biodiesel. Background technique [0002] The importance of energy as a key driving force to promote the development of the national economy is well known. With the shrinking of oil resources, the most important energy. At present, all countries are vigorously developing alternative products of petroleum to meet the needs of economic development. As a substitute for mineral diesel, biodiesel is not only the same as mineral diesel in main performance indicators and practical use, but also has incomparable advantages in environmental protection and raw material resource regeneration. Biodiesel can not only alleviate human dependence on petroleum, but also a renewable energy source. Based on these characteristics, at present, biodiesel is forming a rapidly developing green industry, and the unique advantages of biodiesel determine its broad applicatio...
