Abstract: 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 reactions in the carbonylation were collected with a
differential tubular reactor. Power law rate models were employed to express the conversion
of ethanol and the yields of ethyl propionate and diethyl ether. The results obtained with
the models were in agreement with the experimental data.
