Title: Comparison of the activity of several solid catalysts on the transesterification in subcritical methanol
Abstract: The activity of several solid catalysts,which catalyzed the transesterification of soybean oil and subcritical methanol to prepare biodiesel,was studied.The effects of different catalysts for the transesterification on the yield of biodiesel were investigated.The results showed that the content of fatty acid methyl esters reached 90% under the reaction condition of 40/1 ratio of methanol to oil,the temperature 180℃,the pressure 2~3MPa,3g catalyst,reaction time of 10min and K2O/γ-Al2O3 as solid catalysts.
