A process for the optomization of the amount of sulfur introduced into a cyclic, or semi-cyclic reforming unit consistant with the dual objective of sulfiding a sulfur-sensitive polymetallic platinum catalyst, and minimizing the average sulfur present in the unit during an operating cycle. In accordance with such process, a sulfur-containing naphtha feed between reactor swings is first hydrofined to reduce the sulfur content of the feed, the product therefrom is then passed through a guard bed or reactor and contacted with a sulfur adsorbent essentially completely remove the feed sulfur to maximize catalyst activity, catalyst stability and C. sub. 5. sup. + liquid yield. At the time of, or just prior to, swinging on-stream a reactor which contains an unsulfided fresh, or unsulfided regenerated, reactivated sulfur-sensitive polymetallic platinum catalyst, the series of reactors is by-passed around the hydrofiner and guard chamber and the product from the hydrofiner fed directly into the series of reactors to sulfide the catalyst.

A hydroprocessing process includes two cocurrent flow liquid reaction stages and one vapor stage, in which feed components are catalytically hydroprocessed by reacting with hydrogen. The liquid stages both produce a liquid and a hydrogen-rich vapor effluent, with most of the hydroprocessing accomplished in the first stage. The first stage vapor is also hydroprocessed. The hydroprocessed vapor and second stage vapor are cooled to condense and recover additional product liquid and produce an uncondensed hydrogen-rich vapor. After cleanup to remove contaminants, the hydrogen-rich vapor is recycled back into the first stage as treat gas. Fresh hydrogen is introduced into the second stage. This is useful for hydrotreating heteroatom-containing hydrocarbons.

Hydrocarbonaceous feedstocks admixed with a flow-through catalyst and hydrogen are hydroprocessed in a hydroprocessing reactor containing a captive hydroprocessing catalyst. The flow-through catalyst is continually withdrawn with the hydroprocessed feed from the hydroprocessing reactor. The flow-through catalyst may be an FCC, hydrocracking, isomerization or ring-opening catalyst. In a preferred embodiment, the captive hydroprocessing catalyst contains Co, Ni and/or Mo on an alumina base and the flow-through catalyst is an FCC zeolitic catalyst which is withdrawn with the hydroprocessed feed from the hydroprocessing reactor and then sent to an FCC unit.

Diesel fuel is produced from a feedstock that is at least partially biocomponent in origin. A feedstock is treated in a reactor including one or more hydrotreating zones having a continuous gas phase. The liquid effluent from the hydrotreating zones is then hydroprocessed in a hydroprocessing zone having a continuous liquid phase, such as a hydroprocessing zone in the same reactor. The hydroprocessing zone can be operated under effective catalytic dewaxing conditions.

Processes are provided for producing a diesel fuel product having a sulfur content of 10 ppm by weight or less from feed sources that include up to 50% by weight of a biocomponent feedstock. The biocomponent feedstock is co-processed with a heavy oil feed in a severe hydrotreating stage. The product from the severe hydrotreatment stage is fractionated to separate out a diesel boiling range fraction, which is then separately hydrotreated.

A mineral feed can be hydrotreated in a trickle-bed reactor or other stage in a continuous gas-phase environment. The effluent from the hydrotreatment stage can be separated to remove gas-phase impurities. The remaining liquid effluent from the hydrotreating stage can then be introduced, in total or in part, into a second stage/reactor. A feed of biocomponent origin can also be introduced into the second stage/reactor. The second stage/reactor can be operated to perform deoxygenation of the mixture of biocomponent feed and hydrotreated liquid effluent in a continuous liquid phase environment.

Hydrocarbon feeds can be hydrotreated in a continuous gas-phase environment and then dewaxed in a liquid-continuous reactor. The liquid-continuous reactor can advantageously be operated in a manner that avoids the need for a hydrogen recycle loop. A contaminant gas can be added to the hydrogen input for the liquid-continuous reactor to modify the hydrogen consumption in the reactor.
