Claims
- 1. In a hydrocarbon conversion process of catalytic cracking or catalytic dewaxing comprising contacting the hydrocarbon under hydrocarbon converting conditions with molecular sieve agglomerates to afford a hydroconverted product, the improvement comprising using molecular sieve agglomerates with improved transport properties prepared by the method comprising coating molecular sieve particles with an organic polymer, fixing the organic polymeric coating to the surface of the molecular sieve particles so as to produce a non-migratory coating thereon, binding the coated molecular sieve particles with a binding agent which is at least one inorganic oxide, forming the agglomerates of molecular sieve particles, and removing the organic polymeric coating by calcination.
- 2. The process of claim 1 where the hydrocarbon conversion process is catalytic cracking effected at a temperature between 850.degree. and 1100.degree. F., a pressure of 0-50 psig, and a liquid hourly space velocity of 0.5 up to about 10, and the molecular sieve is zeolite Y.
- 3. The process of claim 1 where the hydrocarbon conversion process is catalytic dewaxing performed under a total hydrogen pressure of between 15 and 3000 psig, a temperature between about 200 and about 475.degree. C. and a liquid hourly space velocity between about 0.1 and about 20, and the molecular sieve is a silicoaluminophosphate.
- 4. The process of claim 3 where the molecular sieve agglomerates have deposited thereon at least one Group VIII metal.
- 5. The process of claim 4 where the molecular sieve agglomerates also have deposited thereon a compound of a metal selected from the group consisting of molybdenum, nickel, vanadium, and zinc.
