Study on Kinetics of Transesterification of Biodiesel in Zanthoxylum bungeanum seed Oil Ethyl Ester

Abstract

Zanthoxylum bungeanum seed oil (ZSO) was the by-product of the zanthoxylum industry, and was a kind of cheap and abundant source in china, which can be great potential of use as a feedstock for biodiesel production in terms of reducing the producing cost. Kinetics of Transesterification of Biodiesel from Zanthoxylum bungeanum seed Oil Ethyl Ester using Sodium ethoxide as an alkaline catalyst was studied in this paper. The results showed that the progression of transesterification was grade 1.5, the reaction activation energy was 17.876kJ•mol-1 and the pre-exponential factor was 0.8521L/(mol•min). The contrast between experimental value and predicted value displayed the dynamics model had a good veracity, and can be applied for predicting reaction rate of progress.
