Abstract:
The present disclosure relates to a process for reducing the amount of carbon disulphide (CS2) in a hydrocarbon feed containing C5-C8 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 CS2 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 CS2 content less than 2 ppm. The amine functionalized anion exchange resin can be regenerated from the solid mass.
