Abstract: Heavy oil feeds are hydroprocessed in the presence of a solvent and in the presence of a catalyst with a median pore size of about 85 ? to about 120 ? under conditions that provide a variety of benefits. The solvent can be an added solvent or a portion of the liquid effluent from hydroprocessing. The processes allow for lower pressure processing of heavy oil feeds for extended processing times or extended catalyst lifetimes be reducing or mitigating the amount of coke formation on the hydroprocessing catalyst.

Abstract: Systems and methods are provided for processing a heavy oil feed, such as an atmospheric or vacuum resid, using a combination of solvent assisted hydroprocessing and slurry hydroconversion of a heavy oil feed. The systems and methods allow for conversion and desulfurization/denitrogenation of a feed to form fuels and gas oil (or lubricant base oil) boiling range fractions while reducing the portion of the feed that is exposed to the high severity conditions present in slurry hydroconversion.

Abstract: Deactivation of a zeolite catalyst during its use to catalyse the oligomerisation of olefins, is often believed to be a result of the formation of high boiling polymers as by-products. These by-products can remain on the catalyst and undergo further conversion to higher molecular weight polymers, which resemble heavy tars and in some cases even have the appearance of coke-like material. These materials can coat the catalyst particles and plug pores in the catalyst, thereby causing catalyst deactivation. The invention relates to an improved method for regenerating such a catalyst.

Abstract: A process for the oligomerization of olefins includes treating, e.g., water washing, an olefin-containing hydrocarbon stream to lower the concentration of an organic nitrogen-containing Lewis base contained therein until the treated hydrocarbon stream is substantially free of the Lewis base; and subsequently contacting the treated hydrocarbon stream with a molecular sieve catalyst to produce a product including at least one oligomer.

Abstract: Methods are provided for processing crude oil feeds with reduced or minimized energy usage, reduced or minimized numbers of processing steps, improved allocation of hydrogen, and reduced or minimized formation of low value products. The methods reduce or minimize the use of vacuum distillation, and in many aspects reduce or minimize the use of both atmospheric and vacuum distillation. The methods also reduce or minimize the use of coking and fluid catalytic cracking processes.

Abstract: Provided is a hydrocarbon tar. The tar has 75 wt % or more of aromatics of 10 carbons to 75 carbons based on the total weight of the tar. The aromatics exhibit 40% to 80% aromaticity. The tar has a boiling point of from 300° F. to 1350° F. There is also a fuel oil composition having the tar therein. There are also processes for making the hydrocarbon tar.

Abstract: This invention is directed to a process for producing a hydroprocessed product. The invention is particularly advantageous in that substantially less hydrogen is absorbed during the process relative to conventional hydroprocessing methods. This benefit is achieved by using a particular solvent as a co-feed component. In particular, the solvent component contains at least one single ring aromatic compound and has a relatively low boiling point range compared to the heavy hydrocarbon oil component used as another co-feed component.

Abstract: In a process for oligomerizing an olefinic hydrocarbon feedstock comprising at least 65 wt % olefins and/or sulfur-containing molecules, the feedstock is contacted under oligomerization conditions with (a) a first unidimensional 10-ring molecular sieve catalyst and (b) a second multidimensional crystalline molecular sieve catalyst. The first and second catalysts may be contained in separate reactors or as separate beds in a single reactor.

Abstract: The invention concerns integration of hydroprocessing and steam cracking. A feed comprising crude or resid-containing fraction thereof is treated by hydroprocessing and visbreaking and then passed to a steam cracker to obtain a product comprising olefins.

Abstract: The invention relates to series reactor beds containing different oligomerization catalysts and having independent temperature control, and processes for the oligomerization of light olefins to heavier olefins using such series reactor beds.

Abstract: The invention is directed to a process comprising feeding high TAN feedstreams to a steam cracker, whereby naphthenic acids in the feedstreams are substantially converted to CO, CO2, and low amounts of smaller acids (e.g., formic, acetic, propionic, and butyric acids). The feedstream is preferably a high TAN feedstream comprising crude or high TAN feedstream which has previously been subjected to a refinery process to remove resid.
