  • Patent number: 10214465
    Abstract: The present subject matter describes processes for increasing overall aromatics and xylenes yield in an aromatics complex. More specifically, the process for increasing overall aromatics and xylenes yield in an aromatics complex accomplishes the increased yields by incorporating an A8-A10 isomerization step into the aromatics complex. This isomerization integration increases the para-xylene.

  • Publication number: 20160312127
    Abstract: Process for minimizing the amount of catalyst fines in a flue gas from a catalyst regenerator. Pyrolysis oil is injected into the reaction zone, preferably downstream from the feedstream inlet. The catalyst fines will be passed along with the hydrocarbon effluent stream and can be removed with a filter or other similar device. The amount of pyrolysis oil can be controlled, for example, based upon the opacity of the flue gas from the catalyst regenerator, or based upon the amount of catalyst injected into the reaction zone.

  • Publication number: 20160312134
    Abstract: A method for producing jet-range hydrocarbons includes passing a renewable olefin feedstock comprising C3 to C8 olefins to an oligomerization reactor containing a zeolite catalyst to produce an oligomerized effluent, separating the oligomerized effluent into at least a light stream, and a heavy olefin stream. At least a first portion of the heavy olefin stream is recycled to the oligomerization reactor to dilute the renewable olefin feedstock. portion of heavy olefin stream may be hydrogenated and separated to provide a jet range hydrocarbon product.

  • Patent number: 9422478
    Abstract: Char-handling processes for controlling overall heat balance, ash accumulation, and afterburn in a reheater are provided. Carbonaceous biomass feedstock is pyrolyzed using a heat transfer medium forming pyrolysis products and a spent heat transfer medium. The spent heat transfer medium is separated into segregated char and char-depleted spent heat transfer medium. The char-depleted spent heat transfer medium is introduced into a dense bed of heat transfer medium fluidized by a stream of oxygen-containing regeneration gas. All or a portion of the segregated char is combusted in the dense bed using the stream of oxygen-containing regeneration gas. A portion of the segregated char may be exported out of the pyrolysis system to control the overall heat balance and ash accumulation.

  • Patent number: 9193921
    Abstract: 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.

  • Patent number: 9193644
    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.

  • Patent number: 9163199
    Abstract: A linear alkyl benzene product and production of linear alkylbenzene from a natural oil are provided. A method comprises the step of deoxygenating the natural oils to form a stream comprising paraffins. The paraffins are dehydrogenated to provide mono-olefins. Then, benzene is alkylated with the mono-olefins under alkylation conditions to provide an alkylation effluent comprising alkylbenzenes and benzene. Thereafter, the alkylbenzenes are isolated to provide the alkylbenzene product.
