ABSTRACT:
A process is disclosed for dewaxing a waxy hydrocarbon feedstock and for upgrading the olefinic interstage by-product to a high-octane gasoline blending stream. Waxy hydrocarbon feedstock is catalytically dewaxed until the catalyst is deactivated. Hydrogen-rich gas or, optionally, oxygen-containing gas, is then circulated to at least partially reactivate the catalyst. The interstage by-product, stored during the dewaxing run, is then upgraded in the reaction zone to a high-octane gasoline blending component.
