Abstract: A process and apparatus is disclosed for pretreating a hydrocarbon stream in a hydrotreating reactor and separating the diesel materials from the pretreated effluent before the heavier liquid materials are fed to a hydrocracking unit. Thus diesel materials are preserved but recovered along with the hydrocracked effluent. A recovered diesel stream can be sent to a hydrotreating unit to improve its cetane rating.

Abstract: A process for converting polycyclic aromatic compounds to monocyclic aromatic compounds includes pyrolyzing a coal feed to produce a coke stream and a coal tar stream. The coal tar stream is cracked, and the cracked coal tar stream is fractionated to produce an aromatic fraction comprising the polycyclic aromatic compounds. The process further includes hydrocracking the aromatic fraction to partially hydrogenate at least a first portion of the aromatic fraction, and to open at least one ring of a second portion of the aromatic fraction to form the monocyclic aromatic compounds from the polycyclic compounds, and recycling the first portion of the aromatic fraction.

Abstract: 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.

Abstract: 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° C. to about 180° 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.

Abstract: A process for pyrolyzing coal using a recycled hydrogen donor includes introducing a coal feed to a pyrolysis zone and heating the coal feed to a temperature of about 300° C. in the absence of hydrogen. A hydrogen donor solvent is introduced to the pyrolysis zone after the coal feed is heated to about 300° C., and the temperature of the coal feed and the hydrogen donor solvent is increased to about 475° C., while increasing a pressure in the pyrolysis zone to at or above a vapor pressure of the hydrogen donor solvent. At least an aromatic hydrocarbon rich fraction is separated from the coal tar stream and hydrogenated. The hydrogenated aromatic hydrocarbon rich fraction is recycled to the pyrolysis zone as the hydrogen donor solvent.

Abstract: A process for producing a high quality distillate that meets the ultralow sulfur, cold flow, and distillation requirements. The feed stream is first hydrotreated and dewaxed in the same reactor to provide a hydrotreated and dewaxed effluent. The hydrotreated and dewaxed effluent is separated in a separation zone into a liquid and a vapor phase, the vapor phase comprising a hydrogen containing gas that can be recycled. The liquid phase is separated into at least a diesel stream and a heavy hydrocarbon stream. The heavy hydrocarbon stream is hydrocracked and the hydrocracked effluent may be passed to the reactor for hydrotreating and dewaxing or passed to the separation zone with the hydrotreated and dewaxed effluent.
