摘要： A catalytic hydrocracking process for the production of ultra low sulfur diesel wherein a hydrocarbonaceous feedstock is hydrocracked at elevated temperature and pressure to obtain conversion to diesel boiling range hydrocarbons. The resulting hydrocracking zone effluent is hydrogen stripped in a stripping zone maintained at essentially the same pressure as the hydrocracking zone to produce a first gaseous hydrocarbonaceous stream and a first liquid hydrocarbonaceous stream. The first gaseous hydrocarbonaceous stream containing diesel boiling range hydrocarbons is introduced into a desulfurization zone and subsequently partially condensed to produce a hydrogen-rich gaseous stream and a second liquid hydrocarbonaceous stream containing diesel boiling range hydrocarbons. The first liquid stream is separated to produce a third liquid hydrocarbonaceous stream containing diesel boiling range hydrocarbons which is also introduced into the desulfurization zone. An ultra low sulfur diesel product stream is recovered.

摘要： A catalytic hydrocracking process which provides for the simultaneous production of LPG and distillate hydrocarbons. The feedstock is introduced into a denitrification and desulfurization zone and then passed directly to a hot, high pressure stripper utilizing a hot, hydrogen-rich stripping gas to produce a first liquid stream boiling in the range of the feedstock and a first vapor stream comprising hydrocarbonaceous compounds boiling at a temperature below the boiling range of the feedstock. The first liquid stream is hydrocracked in a first hydrocracking zone and then passed to the denitrification and desulfurization zone. At least a portion of the first vapor stream is condensed to produce a second liquid stream comprising hydrocarbonaceous compounds boiling at a temperature below the boiling range of the feedstock. At least a portion of the second liquid stream is hydrocracked in a second hydrocracking zone containing a second hydrocracking catalyst to produce LPG boiling range hydrocarbonaceous compounds.

摘要： The invention is a hydrocracking process which employs a small reactor-containing hydrotreating catalyst to reduce the recombinant mercaptan content and/or smoke point of a product recovered from the effluent of the hydrocracking reactor. The entire effluent of the hydrocracking reactor is first cooled by indirect heat exchange and then passed through the hydrotreating catalyst. The effluent of the hydrotreating catalyst then continues throughout the customary cooling and separation steps employed in the product recovery system.

摘要： A process for the simultaneous production of lubricating blending stocks by means of hydrocracking a hydrocarbon feedstock in a first hydrocracking zone to convert at least a portion of the heavy hydrocarbon feedstock to produce an effluent stream containing lube oil boiling range hydrocarbons. One portion of the effluent stream is directly removed from the first hydrocracking zone to produce high quality lube oil blending stocks. Another portion of the effluent stream from the first hydrocracking zone is directly introduced into a second hydrocracking zone without intermediate separation. The second hydrocracking zone is utilized to further crack the feed to produce motor fuel.
