(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.

摘要： A process for the production of lube oil basestock wherein a high boiling hydrocarbonaceous feedstock is hydrocracked to produce hydrocarbons boiling in the range of lube oil basestock and the resulting hydrocracker effluent is hot, hydrogen stripped to remove lower boiling hydrocarbons and hydrogen sulfide before being introduced into a hydrodewaxing zone. In a preferred embodiment the hot hydrogen stripper contains a hydrogenation zone conducted at “sweet” hydrogenating conditions which permits the subsequent use of sulfur sensitive catalysts in downstream reaction zones including hydrodewaxing and hydrofinishing reaction zones. Preferably, the effluent from the hydrodewaxing reaction zone is immediately further processed in a hydrofinishing reaction zone.

摘要： Heavy hydrocarbons are upgraded to higher value distillates in a hydrocarbon conversion process which employs several parallel on-stream reaction zones which each contain both hydrotreating and hydrocracking catalyst beds. The feed and liquid recycled from the bottom of the reaction zone is charged to the top of the uppermost catalyst bed. Hydrogen flow in the reaction zones is countercurrent to the descending liquid, and products are removed as vapor. The flow of feed to one of the reaction zones is periodically stopped to allow sequential on-stream hydrogenative regeneration of the catalysts within the reaction zones. This allows continuous commercial operation at conditions which are otherwise unfeasible.

摘要： A hydrocracking process wherein a hydrocarbonaceous feedstock and a hot hydrocracking zone effluent containing hydrogen is passed to a denitrification and desulfurization reaction zone to produce hydrogen sulfide and ammonia to thereby clean up the fresh feedstock. The resulting hot, uncooled effluent from the denitrification and desulfurization zone is hydrogen stripped in a stripping zone maintained at essentially the same pressure as the preceding reaction zone with a hydrogen-rich gaseous stream to produce a vapor stream comprising hydrogen, hydrocarbonaceous compounds boiling at a temperature below the boiling range of the fresh feedstock, hydrogen sulfide and ammonia, and a liquid hydrocarbonaceous stream.

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.
