Aspen Plus software was used to study new preparation process of p-xylene from methanol and toluene. Effect of feeding way and ratio of reactants, reaction temperature, catalyst and rectifying column plate number on conversion rates of methanol and toluene, catalysis results and extraction yield of p-xylene was investigated. The results show that the conversion rate of reactants with gas state feeding way after vaporization is higher than that with the direct solid feeding way, the effect of energy saving can be achieved. The best reaction conditions are as follows:feeding ratio of methanol and toluene 1.71:1, ratio of carrier gas hydrogen and water 1.77:1, ratio of silica and alumina in the catalyst 5:1, reaction temperature 310 ℃.
