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 t o 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~ C to 1000~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 alkylate d aromatic compounds, cracking and dewaxing. |
