The present disclosure relates to a process for reducing the amount of carbon disulphide (CS) in a hydrocarbon feed containing C-Cfractions. 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 CSand 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 CScontent less than 2 ppm. The amine functionalized anion exchange resin can be regenerated from the solid mass.

The present invention relates a metal passivator additive comprising: a rare earth component; alumina; clay; colloidal silica; and a zeolite having high silica to alumina ratio. The present invention also relates to a process for preparing a metal passivator additive, said process comprising: preparing a rare earth slurry by mixing rare earth component with water; obtaining an alumina gel by treating alumina slurry with an acid, wherein the alumina slurry is prepared by mixing alumina and water; mixing the alumina gel and the rare earth slurry to obtain a slurry mixture; adding a colloidal silica to the slurry mixture; preparing a clay slurry by mixing clay and a dispersant; combining the clay slurry and the slurry mixture to obtain a rare earth-binder-filler slurry; obtaining an additive precursor slurry by mixing a zeolite having high silica to alumina ratio to the rare earth-binder-filler slurry; spray-drying the additive precursor slurry to obtain a spray-dried product; and calcining the spray-dried product to obtain the metal passivator additive.
