A hydroprocessing catalyst with improved performance has been produced that involves an intimately mixed unsupported metal oxide with a zeolite or other acid function. The intimate mixing allows an intimate interaction between the unsupported metal oxide and the acid function. The hydroprocessing catalyst may be used alone or may be incorporated with a portion of a conventional hydrocracking catalyst.

A process for transalkylating a coal tar stream is described. A coal tar stream is provided, and is fractionated to provide at least one hydrocarbon stream having polycyclic aromatics. The hydrocarbon stream is hydrotreated in a hydrotreating zone, and then hydrocracked in a hydrocracking zone. A light aromatics stream is added to the hydrocracking zone. The light aromatics stream comprises one or more light aromatics having a ratio of methyl/aromatic available position that is lower than a ratio of methyl/aromatic available position for the hydrotreated stream. The hydrocracked stream is transalkylated in the hydrocracking zone.

Hydrocracking process for a hydrocarbon stream

A process for providing aromatics from a coal tar stream. A coal tar stream is provided, and the coal tar stream is fractionated into at least a naphtha range stream. The naphtha range stream is hydrotreated, and the hydrotreated naphtha range stream is separated to provide at least a naphthene rich stream. The naphthene rich stream is reformed or dehydrogenated to convert the naphthene. The dehydrogenated naphthene rich stream may be combined with a portion of a reformed crude oil hydrocarbon stream.

Process for providing aromatics from coal tar

A process for selectively dealkylating aromatic compounds includes providing a coal tar stream comprising aromatic compounds and hydrotreating the coal tar stream to reduce a concentration of one or more of organic sulfur, nitrogen, and oxygen in the coal tar stream, and to hydrogenate at least a portion of the aromatic compounds in the coal tar stream. The process further includes hydrocracking the hydrotreated coal tar stream to further hydrogenate the aromatic compounds and to crack at least one ring of multi-ring aromatic compounds to form single-ring aromatic compounds. The single-ring aromatic compounds present in the hydrocracked stream are then dealkylated to remove alkyl groups containing two or more carbon atoms.

A process for pyrolyzing a coal feed is described. A coal feed is pyrolyzed into a coal tar stream and a coke stream in a pyrolysis zone. The coal tar stream is separated into at least a pitch stream comprising aromatic hydrocarbons. The pitch stream is reacted in a reaction zone to add at least one functional group to an aromatic ring of the aromatic hydrocarbons in the pitch stream. The functionalized pitch stream is recycled to the pyrolysis zone.

Process for pyrolysis of a coal feed

A process for producing alkylated aromatic compounds includes pyrolyzing a coal feed to produce a coke stream and a coal tar stream. The coal tar stream is hydrotreated and the resulting hydrotreated coal tar stream is cracked. A portion of the cracked coal tar stream is separated to obtain a fraction having an initial boiling point in the range of about 60&#xb0; C. to about 180&#xb0; C., and an aromatics-rich hydrocarbon stream is extracted by contacting the fraction with one or more solvents. The aromatics-rich hydrocarbon stream is contacted with an alkylating agent to produce an alkylated aromatic stream, or the aromatics-rich hydrocarbon stream is reacted with an aliphatic compound or methanol in the presence of a catalyst to produce a methylated aromatic stream. The alkylated aromatic stream, the methylated aromatic stream, or both are separated into at least a benzene stream, a toluene stream, and a xylenes stream.

Process for producing alkylated aromatic compounds

One exemplary embodiment can be a slurry hydrocracking process. The process can include providing one or more hydrocarbon compounds having an initial boiling point temperature of at least about 340&#xb0; C., and a slurry catalyst to a slurry hydrocracking zone. The slurry catalyst may have about 32-about 50%, by weight, iron; about 3-about 14%, by weight, aluminum; no more than about 10%, by weight, sodium; and about 2-about 10%, by weight, calcium. Typically, all catalytic component percentages are as metal and based on the weight of the dried slurry catalyst.

Slurry hydrocracking process

A process is disclosed for converting heavy hydrocarbon feed into lighter hydrocarbon products. The heavy hydrocarbon feed is slurried with a catalyst comprising molybdenum supported on a base, such as boehmite or pseudo-boehmite alumina. Iron oxide may also be in the base. The base is preferably bauxite. The heavy hydrocarbon slurry is hydrocracked in the presence of the catalyst to produce lighter hydrocarbons.

A method and apparatus for converting glycerol into propylene glycol by directing a basic glycerol containing feed and a hydrogen containing gas into a reaction zone including a fixed bed of catalyst that is operating at glycerol conversion conditions where the reactor includes and at least one quench zone and directing a quench material into the quench zone.

The heavy hydrocarbon feed is slurried with a catalyst comprising iron oxide and alumina to form a heavy hydrocarbon slurry and hydrocracked to produce lighter hydrocarbons. Performance of the iron oxide and alumina catalyst at high mean particle diameters is comparable to performance at low mean particle diameters.
