HYDROCARBON CONVERSION PROCESSES USING NON-ZEOLITIC MOLECULAR SIEVE CATALYSTS

摘要

Methods of removing halogen from non-zeolitic molecular sieve catalysts, the catalyst produced from such methods, and the use of such catalysts in hydrocarbon conversion processes. Several processes are disclosed allowing to remove most, if not all, of the halogen contained in the catalysts. The processes comprise steam-treating the catalyst at a temperature of from 400 DEG C to 1000 DEG C. The hydrocarbon conversion processes include the conversion of oxygenates to olefins, the conversion of oxygenates and ammonia to alkylamines, the conversion of oxygenates and aromatic compounds to alkylated aromatic compounds, cracking and dewaxing.
