Transesterification of waste cooking oil using FeCl3-modified resin catalyst and the research of catalytic mechanism

Biodiesel production from waste cooking oil using FeCl3-modified resin as heterogeneous catalyst was investigated. In the optimum conditions, Fe load rate of resin of 10.97%. Comparison of effects of modified resin, unmodified resin, and homogeneous catalyst (FeCl3·6H2O) for the transesterification of waste cooking oil and methanol revealed that the transesterification rate of modified resin as catalyst reached 92.13%, which was 13.37% and …
