Abstract: Heavy waxy oil is dewaxed by a mild cracking and isomerization process using a catalyst comprising SSZ-32 and at least one Group VIII metal. The heavy oil contains naphthenic wax, which includes only a relatively small amount of normal alkanes. Naphthenic wax containing a minor amount of oil may also be dewaxed using the process.
