Abstract: Aspen Plus software was applied to the simulation of etherification of reactive C5 alkene in light gasoline with methanol producing tert-amyl methyl ether (TAME) by catalytic distillation (CD) process in this work. Homogeneous and heterogeneous reaction kinetic models were applied in the fixed bed pre-reactor and CD column; both the equilibrium and non-equilibrium models were adopted in the CD column. After been validated by experimental data, this model was applied to the light gasoline etherification process analysis, including the influence of space velocity, reaction temperature, methanol appending, feeding position, as well as the catalyst packing properties on the etherification efficiency. The optimized operating parameters were obtained from the model analysis, such as space velocity of 2-3 h-1, reaction temperature of 70℃ and so forth，which will be helpful for the optimization of light gasoline etherification operation, facture of suitable catalyst packets and process design as well.
