An In-situ FTIR Study of the Methanol to Hydrocarbons Reaction Over Zeolite Catalysts

摘要

This thesis investigates several different types of zeolites during the conversion of methanol to hydrocarbons, and examines the effects of the differences between them. All samples were characterized by SEM, XRD, ICP-MS and BET to confirm that they were as reported by the manufacturers. The samples were investigated by in-situ FTIR during water desorption and during reaction while feeding methanol at 350 degrees. The effluents of the reactions were analyzed by on-line GC-MS-FID. The further experiments were performed while feeding methanol at four different temperatures.
