过渡金属掺杂亚铁锌双金属氰化物催化合成生物柴油的研究
Synthesis of biodiesel by transition metal doped Fe/Zn double metal cyanide complex catalysts
摘要
Abstract
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 (Il)-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.关键词
