| Abstract: | Solid base catalyst,CaO-zeolite was prepared and applied in the transesterification preparation of biodiesel.The effect of five extraction factors on the process were studied by orthogonal test,and the optimum conditions for the preparation of the biodiesel were showed as follows:catalyst was preparated at 500 ℃,the amount of catalyst was 4% of fuel oil quality,ratio of alcohol to oil was 9:1,and reaction 3.5 h at 70 ℃;Under these conditions,the biodiesel yield was up to 98%.Then soild base catalyst was characterized by FT-IR,TG-DSC and XRD. |
