Preliminary Approach for New Supercritical Biodiesel Production from Plant Oils with Neutral Esters

研究了以碳酸二甲酯为中性酯的植物油一步超临界生产BDF的方法，并对其生产脂肪酸甲酯（FAME）和副产物碳酸甘油的反应条件进行了分类。并对超临界二步法生产bdf的最佳工艺条件进行了分类。所获得的FAME可满足日本、美国等国的BDF燃料标准要求。对其他碳酸二烷基酯也进行了研究，得到了多种脂肪酸烷基酯。因此，世界上首次建立了以碳酸二烷基酯为原料的非催化超临界BDF生产方法。

One-step supercritical BDF production method from plant oils was studied with dimethyl carbonate as one of the neutral esters, and its reaction condition toproduce fatty acid methyl esters (FAME) and glycerol carbonate as by-productswere classified. In addition, optimum condition of two-step supercritical BDFproduction method was also classified. The obtained FAME could satisfy the BDF fuel standard requirements in Japan, US etc. The other dialkyl carbonates were alsostudied, and various fatty acid alkyl esters were found to be produced. Thus, non-catalytic supercritical BDF production method was first in the world established with dialkyl carbonates.
