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： Heavy hydrocarbons are upgraded to higher value distillates in a hydrocarbon conversion process which employs several parallel reaction zones which each contain both hydrotreating and hydrocracking catalyst beds. The feed and liquid recycle from the bottom of the reaction zone is charged to the top of the uppermost catalyst bed. Hydrogen flow is countercurrent to the descending liquid, and products are removed overhead through vapor-liquid contactors. 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 zone.

摘要： A feed stream is first processed in a hydrotreating reaction zone and then the effluent is separated into three fractions in an augmented first high pressure separator. Controlled portions of the middle and heavy boiling point range hydrocarbon fractions from this separator are recycled through a low conversion hydrocracking zone, while the remaining portions of these two fractions are passed into a second high pressure separator for recovery. The recycled hydrocarbons flow into a hydrocracking zone and the effluent of this zone flows into the hydrotreating reaction zone.

摘要： A process to provide a multiplicity of hydrocracking reaction zones containing hydrocracking catalyst wherein the catalyst is rejuvenated or reactivated while the process unit remains on-stream by the periodic exposure of partially spent catalyst to hot recycle gas containing hydrogen. The hydrocracking catalyst always operates at "near" fresh activity and selectivity thereby resulting in more stable temperature, yield and product quality performance.

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： In an atmospheric fractionator, the number of theoretical stages are increased in the upper light distillate flash zone and in the middle heavy distillate flash zone. The middle distillate pumparound circuit has been eliminated. The reflux to distillate ratio for the light distillate as well as the effluent feed temperature have been substantially increased. As a result, increased yields for middle distillate (e.g. kerosene) and heavy distillate (eg diesel) have been achieved which more than offset the increased energy consumption used for the higher feed temperature In the example of hydrocracking technology, the improved fractionation has benefits in the hydrocracking unit outside of the fractionation unit Increased fractionation efficiency reduces the severity in the hydrocracking unit reactor catalyst and less hydrogen is consumed. The invention can be applied to several other refining technologies besides hydrocracking.
