Simulating and Analysis of Reactor for Selective Hydrogenation of Acetylene

Kinetic rate equations for selective hydrogenation of acetylene and ethylene were proposed,where,reaction order and activation energy were collected from the literature.For estimation and evaluation of parameters in the kinetic rate equations,Aspen program was used.The optimal temperature for the selective hydrogenation of acetylene was 45～80 ℃.Simulating the reactor for the selective hydrogenation of acetylene in rich ethylene feed by using the Aspen program indicated results were in accord with actual running data.The performance of a commercial catalyst was studied.Guidelines for optimal operation of the reactor were proposed.
