Abstract
Disclosed is a hydrocracking process employing a plurality of reaction zones wherein at least one reaction zone contains a small nominal size hydrocracking catalyst (10 to 16 U.S. Sieve mesh size) and wherein the catalyst situated upstream of the small nominal size hydrocracking has a particle size greater than the small nominal size hydrocracking catalyst.
