Abstract
The present invention pertains to a process for the hydroprocessing of heavy hydrocarbon feeds, preferably in an ebullating bed process, by contacting the feed with a mixture of two hydroprocessing catalysts meeting specified pore size distribution requirements. The process combines high contaminant removal with high conversion, low sediment formation, and high process flexibility.
