醋酸催化加氢制乙醇Pt促进的Co基催化剂研究
Study on Pt-promoted Co catalysts for hydrogenation of acetic acid to ethanol
摘要
Abstract
Silica supported Pt-promoted Co catalysts were prepared by incipient wetness impregnation and characterized by XRD and BET. The effects of the loading amount of active metal Co and promoter Pt and the calcination temperature on the catalytic performance of the catalysts for the catalytic hydrogenation of acetic acid to ethanol were investigated in an integral reactor, and the operation conditions of the hydrogenation reaction were optimized. The results showed that the catalysts containing Co of 25%-30%and Pt of 0.5% by mass and using the silica calcined at 550℃ as support exhibited excellent catalytic activity, and under the optimized reaction conditions of 300℃, 5.0MPa, LHSV of 0.4h-1 and hydrogen/acetic acid molar ratio of 25, the conversion of acetic acid could reach more than 98%with a selectivity of ethanol of approaching 60%.关键词
