Nghiên cứu quá trình chuyển hóa dầu vi tảo thành biodiesel trên các hệ xúc tác dị thể lưỡng chức năng MCS

Abstract

Biodiesel was synthesized from microalgal oil typed Botryococcus using a bi-functional heterogeneous catalyst mesoporous calcium containning silicate (MCS). The microalgal oil owned a very large amount of free fatty acid. The conditions for the reactions were controlled such as temperature, time, catalyst dosage, methanol/oil molar ratio and agitation speed. The results revealed that the optimum conditions should be temperature of 63 ^oC, reaction of 24 hours, catalyst dosage of 5 %wt, methanol/oil molar ratio of 45/1 and stirring speed of 450 rpm. The conversion of the reactions was 95.3 %.

Keywords. Biodiesel, mesoporous calcium containing silicate, bi-functional catalyst.
