Regeneration of ZSM-5 type catalyst with a source of alkali or alkaline earth metal cations or ammonia |
摘要 |
A novel method is provided for regenerating deactivated crystalline zeolite catalysts at low temperature. The organic residue is contacted with a source of alkali or alkaline earth metal cations, or a source of ammonia, and the organic residue, including nitrogenous compounds, is extracted with an organic solvent. The method is particularly useful with deactivated ZSM-5 type dewaxing catalyst.
