Abstract:

A two-stage hydrotreating process is disclosed wherein a hydrocarbon stream is first desulphurized followed by a dehydrogenation step, which process comprises in combination contacting the feed and hydrogen over a hydrotreating catalyst at hydrotreating conditions, heating the hydrotreated effluent and hydrogen-rich gas from the hydrotreating reactor and contacting said effluent and hydrogen gas over a hydrotreating catalyst in a post-treatment reactor at a temperature sufficient to increase the polyaromatic hydrocarbon content and lower the hydrogen content of said effluent.

Abstract:

Partial conversion hydrocracking process comprising the steps of(a) hydrotreating a hydrocarbon feedstock with a hydrogen-rich gas to produce a hydrotreated effluent stream comprising a liquid/vapour mixture and separating the liquid/vapour mixture into a liquid phase and a vapour phase, and(b) separating the liquid phase into a controlled liquid portion and an excess liquid portion, and(c) combining the vapour phase with the excess liquid portion to form a vapour plus liquid portion, and(d) separating an FCC feed-containing fraction from the controlled liquid portion and simultaneously hydrocracking the vapour plus liquid portion to produce a diesel-containing fraction, orhydrocracking the controlled liquid portion to produce a diesel-containing fraction and simultaneously separating a FCC feed-containing fraction from the vapour plus liquid portion. The invention also includes an apparatus for carrying out the partial conversion hydrocracking process.

Assignee:

Union Oil Company of California - Los Angeles CA

International Classification:

C10G 4508

US Classification:

208 59

Abstract:

High quality lubricating oil base stocks are produced from crude oils that contain significant concentrations of aromatic compounds in their higher boiling fractions. First, the crude is fractionated. After the residua fraction has been deasphalted, it is combined with the gas oil fraction. The resultant combined fraction is hydrocracked. The hydrocrackate is separated into a light fraction and a heavy fraction. The heavy fraction is hydrodewaxed, then hydrofinished. The hydrofinished product is combined with the light fraction and distilled into products including middle distillate fuel products and lubricating oil base stocks. The lubricating oil base stocks have high VI.

Abstract:

A process including (a) directing a hydrocarbon mixture to contact a material catalytically active in hydrocracking under hydrocracking conditions, (b) providing a first hydrocracked product, (c) directing an amount of the first hydrocracked product and an amount of a converted hydrocracked product to a product separation step separating it into one or more products and a recycle oil having a higher boiling point than the products, (d) directing the recycle oil to contact a second material catalytically active in hydrocracking under hydrocracking conditions providing a second hydrocracked product, (e) directing at least an amount of the second hydrocracked product as feed to a second separation step, separating the second hydrocracked product in at least two fractions, a converted hydrocracked product and an unconverted oil an unconverted oil having a higher average boiling point than the recycle oil, (f) withdrawing at least an amount of the unconverted oil as purge.
