Sulfur removal from molecular-sieve catalyst |
摘要 |
A sulfur-sensitive catalyst which has been deactivated by accumulating sulfur on the catalyst is desulfurized by contact with ammonia at high temperature. The technique is particularly effective for reforming catalysts containing a large-pore zeolite which are selective for dehydrocyclization of paraffins. The desulfurization may be combined with regeneration for coke removal from the catalyst.
