%X Effects of transition metals(La,Ce,Zr,Mn) on catalytic performance of double metal cyanide(DMC) catalysts for biodiesel synthesis were studied.The structure and performance of the catalysts were studied using XRD,FT-IR,ICP,BET et al.The experimental results showed that the DMC catalyst prepared by adding 1% of transition metal salts had higher activity.The catalyst with highest catalytic activity was prepared by adding 1% of La(NO3)3·nH2O.Under the conditions of methanol/oil mol ratio of 16∶1,catalyst amount of 2% and temperature of 160 ℃,a high yield(99.3%) of fatty acid methyl esters(FAME) was obtained within 7 h.The analytical results showed that adding 1% of transition metals did not change the molecular formula of Fe(II)-Zn double metal cyanide complex catalysts,while it improved particle dispersion,decreased particle size and increased surface area.This was the reason that transition metals promoted catalysts had higher activity.
