摘要：

n-Butanol is an important raw material and ideal biomass fuel. Conversion of ethanol into n-butanol in different atmospheres was studied using hydroxyapatite (HAP)-supported Ni as a catalyst (Ni/HAP). Ni/HAP was prepared by a sol-gel method and characterized by XRD, BET, ICP-AES, TEM and SEM-EDX. The effects of reaction atmosphere (N2 and H2), Ni loading and reaction conditions on ethanol conversion and n-butanol selectivity were investigated. The results show that the reaction atmosphere has a significant impact on the reaction. Using 12%Ni/HAP as a catalyst in H2 atmosphere under 300℃ with H2 GHSV of 3000 h-1 and ethanol LHSV of 2.0 h-1, ethanol conversion rate of 15.6% and n-butanol selectivity of 83.6% are obtained, and the catalyst performance has no noticeable decline within 128 h. Ethanol conversion, n-butanol selectivity and catalyst stability increase by 2 times, 4.2 times, and 3 times than those in N2 atmosphere, respectively. © 2016, Editorial Board of “Journal of Chemical Engineering of Chinese Universities”.
