摘要： Methods are disclosed for the hydrotreating and hydrocracking of highly aromatic distillate feeds such as light cycle oil (LCO) to produce ultra low sulfur gasoline and diesel fuel. Optimization of hydrotreater severity improves the octane quality of the gasoline or naphtha fraction. In particular, the operation of the hydrotreater at reduced severity to allow at least about 20 ppm by weight of organic nitrogen into the hydrocracker feed is shown to lead to these important benefits. Post-treating of the hydrocracker effluent over an additional hydrotreating catalyst bed may be desired to meet specifications for ultra low sulfur fuel components.

摘要： A process for simultaneously hydrocracking multiple feedstocks wherein a first feedstock is hydrotreated in a hydrotreating zone to produce a hydrotreating zone effluent which is separated to provide a first vaporous hydrocarbonaceous stream and a first liquid hydrocarbonaceous stream. The second feedstock and the first vaporous hydrocarbonaceous stream are hydroprocessed in a hydroprocessing zone to produce a hydroprocessing zone effluent. A third feedstock and the first liquid hydrocarbonaceous stream are hydrocracked in a hydrocracking zone to produce a hydrocracking zone effluent. The hydrocracking zone effluent and the hydroprocessing zone effluent are separated to recover hydrocracked hydrocarbons.

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.

The vapor fraction is passed into a second high pressure separator. A controlled portion of the liquid fraction from the first high pressure separator and the liquid from the second high pressure separator are passed into a hydrocracking zone. The remaining portion of the liquid from the first high pressure separator is passed into the product recovery 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 hydrocarbon fractions are passed into a high severity hydrocracking zone, while the remaining portions of these two fractions are passed into a second high pressure separator for recovery. The effluent of the hydrocracking zone is also fed to the second high pressure separator.

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.
