摘要： 采用浸渍法制备了负载在竹炭 (BC)、柱状煤质炭 (CYC)、果壳炭 (FC)、木质炭 (WC) 和椰壳炭 (CC) 上的 5 种 Ni 基催化剂, 考察了镍分散度、还原性能及催化乙醇气相羰化制丙酸的性能. 用 N2 物理吸附法、X 射线光电子能谱和程序升温脱附等方法研究了活性炭的孔结构特性、表面含氧官能团种类和数量. 结果表明, Ni/CC 的羰化活性最高, 乙醇转化率和丙酸选择性分别为 96.1% 和 93.2%, 而 Ni/BC 的羰化活性最低, 乙醇转化率和丙酸选择性分别为 63.0% 和 32.7%. 催化剂催化羰化性能与其载体活性炭材料的性质密切相关.

Abstract: Different active carbons, i.e. bamboo charcoal (BC), cylindrical coal (CYC), fruit carbon (FC), wood charcoal (WC), and coconut charcoal (CC), were used to prepare Ni/C catalysts for vapor-phase carbonylation of ethanol. The catalytic performance of the catalysts was related to the nature of active carbons and the Ni/CC catalyst showed the maximal activity.

Key words: active carbon, ethanol, vapor-phase carbonylation, propionic acid, surface functional group
