Abstract
The invention disclosed herein is a method of treating middle distillate hydrocarbons to selectively convert tricyclic hydrocarbons to hydrocarbons of better cetane value by means of hydrogenation and cracking. The process is performed in the presence of an intercalated clay catalyst having high temperature stable pillars intermediate layers of the clay. This process achieves a diesel fuel having a higher cetane value than is currently obtainable utilizing molecular sieve catalysts such as a metal impregnated Y zeolite. The tricyclic aromatics are selectively hydrogenated and cracked in preference to accompanying paraffins, isoparaffins, tetralins and decalins.
