ABSTRACT:
A cracking/dewaxing process is provided with a catalyst composition prepared by the steps of (1) mulling, in the presence of water, a crystalline zeolite having less than about 1000 ppm alumina and an Alpha Value of less than about 5 with an inorganic binder, (2) forming the composition of step (1) at a pressure of from 2 to about 50 tons per square inch, (3) calcining the formed composition of step (2), (4) base exchanging the calcined composition of step (3) if it has a sodium content greater than about 0.02 wt. % in order to reduce the sodium content to less than 0.02 wt. %, and (5) calcining the product of step (4). In a particular embodiment wherein the zeolite has a ZSM-5 type structure, the cracking is selective for waxes and the process is useful for reducing the pour point of fuel oils and lubricants.
