摘要：
The methanol to olefin with iodide method (IMTO) is a potential and alternative route for its mild process conditions, which produces methyl iodide as intermediate. Methanol can be highly converted, yielding high rates of selectivity to light olefins, by its reaction over varies modified ZSM-5 zeolites. Efforts have been taken to optimize the reaction with respect to selectivity of olefin and conversion of methanol. Based on the analysis of gas chromatography, the following operating conditions were obtained: 250 degrees C of reaction temperature, CH3OH:HI:H2O=1:1:3 of the molar ratio of raw materials, 2.5 h(-1) of methanol space velocity and 30 ml.min(-1) of nitrogen low rate.
