Kinetics of Vapor-Phase Carbonylation of Ethanol on Ni-Zn/C Catalyst

摘要

A novel heterogeneous Ni-Zn/C catalyst was used for vapor-phase carbonylation of ethanol under atmospheric pressure.Experiments were designed with the elimination of mass-transfer resistances.The data of primary reaction in the carbonylation were collected with a differential tubular reactor.Power law rate models were emplyed to express the conversion of ethanol and the yields of ethyl propionated and diethyl ether.The results obtained with the models were in agreement with the experimental data.
