摘要：

A two-dimensional pseudo-homogeneous dispersion model was employed according to the reaction kinetics and analysis of commercial reactor in order to describe and evaluate the operation conditions of industrial fixed-bed reactor for hydrochlorination of acetylene. The Crank-Nicholson method was used with experiential data from pilot-scale reactor in order to solve the equations. Results showed that the simulation results accorded well with the industrial data. Simulation results showed that the space velocity of acetylene and catalyst performance greatly influenced the distribution of reactor temperature and products when the catalyst activity was low. An expression of the optimum space velocity of acetylene can be deduced by considering the relationship between the space velocity of acetylene and the catalyst activity. The tube wall temperature 98 °C and tube size φ51 mm×3.5 mm is rational at present use by simulation.
