Modelling and simulation of 1,2-dichloroethane production by ethylene oxychlorination in fluidized-bed reactor

摘要

A comprehensive reactor model for ethylene oxychlorination for the production of 1,2-dichlorethane in a fluidized-bed reactor is developed. The model is based on the two-phae theory of fluidization and allows for the change in volumetric gas flow rate in the dense phase due to the change in number of moles accompanying the reaction. The model predictions compared favorably with the industrial data obtained from the literature. The effect of different parameters on the behavior of the system is also investigated. It has been found that the bubble diameter, ethylene molar feed fraction, residence time, and height at minimum fluidiation have signficant effects on the reactor performance.
