Abstract
Abstract A process for the simultaneous dewaxing of high pour point gas oil and upgrading of an aromatic containing naphtha by contact of a mixture of the gas oil and naphtha with a high silica to alumina ratio synthetic aluminosilicate zeolite catalyst, which is derived from a zeolite which was synthesized with an organic cation, incorporating a hydrogenation dehydrogenation component, and a hydrogen atmosphere at about 500* to 1,000*F followed by distillation of the product in order to recover a lower pour point gas oil fraction and a higher octane gasoline fraction.
