The present disclosure relates to a process for reducing the amount of carbon disulphide (CS.sub.2) in a hydrocarbon feed containing C.sub.5-C.sub.8 fractions. The hydrocarbon feed is treated with an amine functionalized anion exchange resin (basic anion exchange resin) to obtain a mixture comprising a liquid fraction containing treated hydrocarbon and a solid mass containing an adduct of CS.sub.2 and the amine functionalized anion exchange resin. The so obtained liquid fraction containing the treated hydrocarbon is separated from the solid mass to obtain the hydrocarbon having CS.sub.2 content less than 2 ppm. The amine functionalized anion exchange resin can be regenerated from the solid mass.

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.

The C.sub.2-C.sub.4 olefms and dienes and/or C.sub.1-C.sub.4 oxygenates in produced gas resulting from the catalytic pyrolysis of hiomass may he upgraded to C.sub.5+ hydrocarbons and/or C.sub.5+ oxygenates in the gaseous phase or in the liquid phase. In addition, the C.sub.2-C.sub.4 olefins and dienes and/or C.sub.1 -C.sub.4 oxygenates in produced water maybe upgraded to C.sub.5+ hydrocarbons and/or C.sub.5+ oxygenates in the gaseous phase.

Methods of separating and purifying products from the catalytic fast pyrolysis of biomass are described. In a preferred method, a portion of the products from a pyrolysis reactor are recovered and purified using a hydrotreating step that reduces the content of sulfur, nitrogen, and oxygen components, and hydrogenates olefins to produce aromatic products that meet commercial quality specifications.
