ABSTRACT:
A hydrocracking process to produce ultra low sulfur diesel by reacting a first hydrocarbon feedstock in a hydrocracking zone, introducing the hydrocracking zone effluent and a second hydrocarbon feedstock having a majority boiling at a temperature greater than 565° C. (1050° F.) into a first desulfurization zone, passing the first desulfurization zone effluent to a hot, high pressure vapor-liquid separator to recover a vaporous hydrocarbonaceous stream and a first liquid hydrocarbonaceous stream, introducing the vaporous hydrocarbonaceous stream and a third hydrocarbonaceous feedstock comprising diesel into a second desulfurization zone, passing the second desulfurization zone effluent to a cold vapor-liquid separator to provide a hydrogen-rich gaseous stream and a second liquid hydrocarbonaceous stream and passing the first and the second liquid hydrocarbonaceous streams to a fractionation zone to produce ultra low sulfur diesel.
