    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.

    摘要: A process for preparing a naphtha reforming catalyst has been developed. The process involves the use of a chelating ligand such as ethylenediaminetetraacetic acid (EDTA). The aqueous solution of the chelating ligand and a tin compound is used to impregnate a support, e.g., alumina extrudates. A platinum-group metal is also an essential component of the catalyst. Rhenium may also be a component. A reforming process using the catalyst has enhanced yield, activity, and stability for conversion of naphtha into valuable gasoline and aromatic products.
