A process is provided for converting a mixture of carbon monoxide and molecular hydrogen to an alcohol mixture, which is separated into a first methanol-containing stream and a second Calcohol-containing stream. The first stream's methanol is reacted to produce a mixture of aromatics and aliphatics. The second stream's Calcohol is converted to hydrocarbon including ethylene and propylene.

[object Object]

Carbon monoxide and molecular hydrogen are converted to an alcohol mixture, which is separated into a first methanol-containing stream and a second Calcohol-containing stream. The first stream's methanol is converted into a propylene-rich product, and the second stream's Calcohol is converted to ethylene and additional propylene.

Production of C2+ olefins

This disclosure relates to the production of xylenes from syngas, in which the syngas is converted to an aromatic product by reaction with a Fischer-Tropsch catalyst and an aromatization catalyst. The Fischer-Tropsch catalyst and aromatization catalyst may be different catalysts or combined into a single catalyst. The aromatic product is then subjected to selective alkylation with methanol and/or carbon monoxide and hydrogen to increase its p-xylene content.

Production of xylenes from syngas

A process and apparatus for cracking a hydrocarbon feed containing resid, comprising: heating a hydrocarbon feedstock containing resid; passing said heated hydrocarbon feedstock to a vapor/liquid separator; flashing said heated hydrocarbon feedstock in said vapor/liquid separator to form a vapor phase and a liquid phase containing said resid; passing at least a portion of said resid-containing liquid phase from said vapor/liquid separator to a thermal conversion reactor operating at 649&#xb0; C. or more, wherein the thermal conversion reactor contains coke particles; and converting at least a portion of said resid into olefins.

Integrated vacuum resid to chemicals conversion process

In a hydrocarbon upgrading process, a hydrocarbon feed is treated in at least one of a steam cracker, catalytic cracker, coker, hydrocracker, and reformer under suitable conditions to produce a first stream comprising olefinic and aromatic hydrocarbons. A second stream composed mainly of Cto C+ olefinic and aromatic hydrocarbons is recovered from the first stream and blended said second stream with a residual fraction from a steam cracker or an atmospheric or vacuum distillation unit to produce a third stream. The third stream is then catalytically pyrolyzed in a reactor under conditions effective to produce a fourth stream having an increased benzene and/or toluene content compared with said second stream and a C-olefin by-product. The C-olefin by-product is recovered and benzene and/or toluene are recovered from the fourth stream.

Process for the production of xylenes and light olefins

A hydrocarbon composition that comprises species of at least 3 different carbon numbers, at least about 95 wt % non-normal hydrocarbons, no greater than 1000 wppm aromatics, no greater than 10 wt % naphthenes, and also has a certain boiling point range; and a process for making the hydrocarbon composition.

Olefin oligomerization and compositions therefrom

The invention relates to the integration of a dehydroaromatization process with the processes for the utilization of associated gas; gases comprising methane and higher hydrocarbons, and/or liquefied natural gas (LNG) production or usage.

Process for methane conversion

The invention relates to hydrocarbon fluids having high purity with respect to at least one of sulfur species, nitrogen species, oxygenated species, and unsaturated species, particularly hydrocarbon fluids low in aromatics, a method of making said hydrocarbon fluids, a catalyst for use in said method, an apparatus whereby said method may be practiced, and uses of said fluids.

Ultra pure fluids

In a process for producing phenol and methyl ethyl ketone, benzene and a Colefin are contacted under alkylation conditions and in the presence of an alkylation catalyst to produce sec-butylbenzene. The sec-butylbenzene is then oxidized to produce an oxidation effluent comprising sec-butylbenzene hydroperoxide and acetophenone. At least part of the sec-butylbenzene hydroperoxide in the oxidation effluent is cleaved to produce phenol and methyl ethyl ketone, while at least part of the acetophenone is hydrogenated to produce at least one of methyl benzyl alcohol, styrene and ethylbenzene.

Process for producing phenol and methyl ethyl ketone

A feedstock containing at least 1 wt % butenes, at least 1 wt % pentenes, at least 1 wt % hexenes, at least 10 wppm Cdienes, at least 10 wppm Cdienes, and optionally at least 10 wppm Cdienes can be selectively hydrogenated over a catalyst (e.g., a noble metal) to form a stream containing 100 wppm to 4000 wppm total dienes. The hydrogenated stream, and an olefinic recycle stream having less than 10 wt. % Cmoieties, can be contacted with a molecular sieve catalyst, e.g., at a recycle to feed ratio between 0.1 and 3.0, at a WHSV of at least 1.0 based on olefin in the feed, and at a reactor &#x394;T no greater than 40&#xb0; F. (22&#xb0; C.), thus forming a reaction product that can then be separated into a distillate, e.g., having from 1 wt % to 30 wt % non-normal Colefins, and the aforementioned olefinic recycle stream.

Feedstock preparation of olefins for oligomerization to produce fuels

A hydrocarbon composition comprises at least 90 wt. % of Cto Cnon-normal olefins, non-normal saturates or combinations thereof based on the weight of the hydrocarbon composition, at least 2 wt. % and not greater than 25 wt. % of Chydrocarbons based on the weight of the hydrocarbon composition, and less than 15 wt. % of C+ hydrocarbons based on the weight of the hydrocarbon composition, wherein said hydrocarbon composition has a specific gravity at 15&#xb0; C. of at least 0.730 and less than 0.775. The composition is produced by oligomerization of at least one Cto Colefin and an olefinic recycle stream containing no more than 10 wt. % of C+ non-normal olefins. The composition is useful in producing fuel blends, such as jet fuel and diesel fuel.

Hydrocarbon compositions useful for producing fuels and methods of producing the same

A process for producing a hydrocarbon composition that comprises contacting a feed stream, that comprises at least one Cto Colefin, and an olefinic recycle stream, that comprises a first olefinic recycle stream and no more than 10 wt % of C+ non-normal olefins, with a molecular sieve catalyst in a reaction zone under olefin oligomerization conditions producing an oligomerization effluent stream; separating the oligomerization effluent stream to produce a first olefinic stream, that has a weight ratio of C&#x2212;/(C-C) molecules from about 0.8 to about 1.2 times the weight ratio of C&#x2212;/(C-C) molecules found in the oligomerization effluent stream, and a first hydrocarbon product stream, that comprises at least 1 wt % and no more than 30 wt % of Cnon-normal olefin; and splitting the first olefinic stream to produce the first olefinic recycle stream and a first purge stream.

Olefin oligomerization

This invention is directed to methods of removing water and other condensable materials, as well as solids particles such as catalyst particles, from olefin product streams so as to reduce fouling in the liquid and vapor separation equipment. In order to reduce fouling or contamination in the condensing or quenching process, this invention includes adding a hydrocarbon to at least a portion of the condensed liquid fraction in an amount that effects separation of the liquid fraction into upper and lower fractions.
