英文摘要：

A continuous flow fixed bed reactor was ethanol to acetonitrile over Co-Ni/γ-Al2O3 catalyst used to study the intrinsic kinetics for the amination of under atmospheric pressure, at reaction temperature in the range of 613 643 K, and the molar radio of ethanol to ammonia ranging from 1 ： 2 to 1 ： 10. The kinetic data were collected in the regime where internal and external particle diffusion resistances were absent by using catalyst in the appropriate average size range, appropriate range of residence time as well as other conditions necessary for plug flow and isothermal behavior in the reactor. Power law models were used to fit the experimental data, and the model parameters were fitted by non-linear regression using MATLAB software. The statistical test results showed that the calculated values based on the model were consistent with the experimental data.
