Abstract: Hydrodeoxygenating a biorenewable feed that is concentrated in free fatty acids with 10-13 carbon atoms at a moderate hydrodeoxygenation ratio that is less than the ratio of hydrodeoxygenation utilized for traditional biorenewable feeds such as vegetable oil or even mineral feedstocks, normal paraffins in the range desired by the detergents industry can be produced. Either hydroisomerization or an iso-normal separation can be performed to provide green fuel streams. Two reactors are proposed, one for hydrodeoxygenation of the biorenewable feed that is concentrated in free fatty acids with 10-13 carbon atoms and the other for a traditional biorenewable feed or even a mineral feed operated at a higher deoxygenation ratio.

Abstract: Processes for co-processing a naphtha stream with a light cycle oil stream are disclosed. The processes include hydrocracking the light cycle oil stream under hydrocracking conditions to provide a hydrocracked effluent stream. A naphtha stream is hydrotreated under hydrotreating conditions to provide a hydrotreated effluent stream. The hydrocracked effluent stream and the hydrotreated effluent stream may be passed to a stripping column to recover a stripping bottom stream. The stripping bottom stream may be passed to a main fractionation column to recover an intermediate naphtha stream.

Abstract: A process for dimerizing and oligomerizing olefins to distillate fuels which subjects oligomerized product to hydrocracking and hydroisomerization in a single reactor to convert heavier oligomers to jet fuel range oligomers. A jet fuel product stream may be taken from a side of a stripping column which produces a heavy drag stream from a bottom of the stripping column to ensure an end point boiling specification is achieved.

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: A process and apparatus 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: 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 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.
