Chemical conversion process.

摘要

A process for catalytically converting a feedstock into a product which comprises: (a) contacting the feedstock with a solid composition comprising an effective amount to promote the chemical conversion of small pore crystalline microporous three dimensional solid catalyst at conditions effective to convert the feedstock into the product and to form carbonaceous deposit material on the solid composition; (b) contacting the carbonaceous deposit material-containing solid composition with regeneration medium at conditions effective to remove only a portion of the carbonaceous deposit material from the solid composition; and (c) repeating step (a) using as at least a portion of the solid composition previously subjected to step (b).
