The present invention relates to a process for removing halogen from a non-zeolitic molecular sieve catalyst, the catalyst produced by the process, and the use of the catalyst in a hydrocarbon conversion process. Various methods are disclosed for removing all or most of the halogen contained in the catalyst. The method includes steam-treating the catalyst at a temperature of 400 to 1,000 ° C. 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, pyrolysis and dewaxing. . |
