Methods that increase production of a liquid transportation fuel blend component by utilizing C5 hydrocarbon streams taken from both a refinery naphtha stream and an NGL fractionator pentanes plus stream. A high vapor pressure pentane fraction from the NGL fractionator is separated to remove isopentane and produce lower vapor pressure commodity natural gasoline. A refinery naphtha stream (that is optionally an FCC naphtha stream) is separated to produce a C5 olefins stream that is then oligomerized to produce an upgraded stream having lower vapor pressure and higher octane rating, then combined with the remainder of the naphtha stream as well as the isopentane stream to produce a gasoline blend component that meets specifications for vapor pressure and octane rating.

Provided herein are catalyst supports, catalyst systems, and methods for making catalyst supports, catalyst systems, and performing chemical reactions with the catalyst systems. The catalyst supports include a zeolite and a binder including non-sodium counterions, such as ammonium counterions and/or potassium counterions. The catalyst systems include the catalyst supports and a catalytic material. The catalyst systems may be used to perform chemical reactions, including reactions of one or more hydrocarbons.

Systems and methods include an aromatics complex (ARC), the ARC in fluid communication with a naphtha reforming unit (NREF) and operable to receive a reformate stream produced by the NREF, and the ARC further operable to separate the reformate stream into a gasoline pool stream, an aromatics stream, and an aromatic bottoms stream; and a hydrodearylation unit operable to receive heavy, non-condensed, alkyl-bridged, multi-aromatic compounds from the aromatic bottoms stream, the hydrodearylation unit further operable to hydrogenate and hydrocrack the heavy, non-condensed, alkyl-bridged, multi-aromatic compounds to produce a stream suitable for recycle to the NREF or the reformate stream, where the hydrodearylation unit is further operable to receive hydrogen produced in the NREF.

A catalyst structure includes a porous support structure, where the support structure includes an aluminosilicate material. Any two or more metals are loaded in the porous support structure, the two or more metals selected from the group consisting of Ga, Ag, Mo, Zn, Co and Ce, where each metal loaded in the porous support structure is present in an amount from about 0.1 wt % to about 20 wt %. In example embodiments, the catalyst structure includes three or more of the metals loaded in the porous support structure. The catalyst structure is used in a hydrocarbon upgrading process that is conducted in the presence of methane, nitrogen or hydrogen.

Improved catalytic reforming processes and systems employ reforming reactors in a more efficient manner and can avoid problems associated with yield loss. A portion of the naphtha feed is pre-reformed for conversion of paraffinic naphtha-range compounds into naphthenes and/or aromatics prior to passing to a reforming unit.

A method of making a multifunctional catalyst for upgrading pyrolysis oil includes contacting a zeolite support with a solution including at least a first metal catalyst precursor and a second metal catalyst precursor, the first metal catalyst precursor, the second metal catalyst precursor, or both, including a heteropolyacid. Contacting the zeolite support with the solution deposits or adsorbs the first metal catalyst precursor and the second catalyst precursor onto outer surfaces and pore surfaces of the zeolite support to produce a multifunctional catalyst precursor. The method further includes removing excess solution from the multifunctional catalyst precursor and calcining the multifunctional catalyst precursor to produce the multifunctional catalyst comprising at least a first metal catalyst and a second metal catalyst deposited on the outer surfaces and pore surfaces of the zeolite support.
