Reactor model to simulate the performance of MWNTs-supported Ni catalysts for the hydrogenation of benzene

Liquid-phase catalytic hydrogenation of benzene using a novel catalyst (Nano-Ni catalyst supported on MWCNTs) was studied in a stainless steel autoclave reactor operating at elevated temperatures and pressures (T=160-200C ,P=35-60 bar). An analytical model for reactor simulation has been employed incorporating vapor-liquid equilibrium, and mass transfer limitations. A number of kinetic equations published in literature have been investigated and the most appropriate for this work have been chosen. The agreement of model predictions with measured data is excellent . The results revealed that the nickle on MWCNTs exhibits high activity for hydrogenation of benzene
