Abstract: A renewable feed that is concentrated linear C10-C13 paraffins is produced by hydrodeoxygenating a renewable feedstock is produced by first hydrotreating the feedstock to remove heteroatoms followed by use of a Group VI or VIII catalyst producing a 10-13 carbon atom product having a high level of linearity. Normal paraffins in the range desired by the detergents industry can be produced.

Abstract: A process for hydrotreating a renewable feedstock with improved carbon monoxide management is disclosed. A mixture of renewable feedstock and hydrocarbon feedstock is treated in a hydrotreating reactor to produce a hydrotreated effluent stream and contacting the hydrotreated effluent stream with a water gas shift catalyst bed to produce a shift reactor effluent stream. The shift reactor effluent stream is passed to a cold separator to recover a cold vapor stream and recycling the cold vapor stream having reduced concentration of carbon monoxide to the hydrotreating zone. The subject matter disclosed provides an improved process and apparatus to reduce the accumulation of CO by converting CO present in the hydrotreated effluent stream to CO2 using the water shift gas reaction.

Abstract: An integrated process for maximizing recovery of LPG is provided. The process comprises providing a hydrocarbonaceous feed comprising naphtha, and a hydrogen stream to a reforming zone. The hydrocarbonaceous feed is reformed in the reforming zone in the presence of the hydrogen stream and a reforming catalyst to provide a reformate effluent stream. At least a portion of the reformate effluent stream and at least one stream comprising C6− hydrocarbons from one or more of a hydrocracking zone, an isomerization zone, and a transalkylation zone is passed to a debutanizer column of the reforming zone to provide a fraction comprising liquid petroleum gas (LPG) and a debutanizer column bottoms stream.

Abstract: The present invention discloses a process and apparatus for selectively hydrogenating diolefins in a cracked stream. The method combines a conversion unit and a recovery section. The recovery section includes the diolefin hydrogenation reactor that is used to selectively hydrogenate the diolefins in the cracked naphtha. The diolefin depleted naphtha may be debutanized to separate the stabilized naphtha and liquefied petroleum gas streams.

Abstract: A process for reducing the sulfur content of FCC naphtha is described. The process includes introducing a FCC naphtha feed to a selective hydrogenation zone to form a hydrogenated feed. The hydrogenated feed is separated into light fraction and a heavy fraction. The heavy fraction is introduced into a selective hydrodesulfurization zone to form a desulfurized stream which contains mercaptans. The desulfurized stream is separated into a mercaptan rich stream and a mercaptan lean stream. The mercaptan rich stream is treated with a caustic extraction process, a hydrodesulfurization reaction zone, a selective hydrogenation process, an adsorption process, or an ionic liquid extraction process to remove at least a portion of the mercaptan compounds to form a second mercaptan lean stream.

Abstract: Processes for pyrolyzing biomass. A catalyst is used to both pyrolyze and deoxygenate the biomass within the pyrolysis zone. A source of carbon monoxide is also passed to the pyrolysis reactor. The source of carbon monoxide may comprise a stream of gas that includes carbon monoxide, or a material capable of generating or being converted in carbon monoxide within the pyrolysis zone. The carbon monoxide may be used as a reactant for a water gas shift reaction or as a reducing agent to remove oxygen from oxygenated hydrocarbons. The catalyst preferably comprises iron (III) oxide.

Abstract: A biorenewable feed that is concentrated in free fatty acids is produced by hydrodeoxygenating a biorenewable feedstock is produced by use of a Group VIII catalyst producing a 10-13 carbon atom product having a high level of linearity. Normal paraffins in the range desired by the detergents industry can be produced. Either isomerization or an iso-normal separation can be performed to provide green fuel streams.

Abstract: An integrated process for maximizing recovery of aromatics is provided. The process comprises passing at least a portion of a xylene column bottoms stream to a heavy aromatics column to provide a heavy aromatics column bottoms stream comprising C9+ aromatics and a heavy aromatics column overhead stream. The heavy aromatics column bottoms stream is passed to a second stage hydrocracking reactor of a two-stage hydrocracking reactor. In the second stage hydrocracking reactor, the heavy aromatics column bottoms stream is hydrocracked in the presence of a hydrocracking catalyst and hydrogen to provide a hydrocracked effluent stream.
