The present disclosure relates to an additive and a catalyst composition for a catalytic cracking process of vacuum gas oil for preparing cracked run naphtha having reduced liquid olefin content, and increased propylene and butylene yields in the LPG fraction. The process makes use of a catalyst composition which is a mixture of an FCC equilibrated catalyst and an additive comprising a zeolite, phosphorus and a combination of metal promoters. The process is successful in achieving high propylene and butylene yields in the LPG fraction along with a lower liquid olefin content and increased aromatic content with increase in RON unit in the resultant cracked run naphtha, as compared to that achieved using an FCC equilibrated catalyst alone.

Additive and a catalyst composition comprising the additive for FCC process

A catalyst composition for isomerization of paraffins includes at least one metal, at least one heteropoly acid and a support material. Further provided are a process for preparation of the catalyst composition and a process for isomerization of paraffins using the catalytic composition.

Catalyst composition for isomerization of paraffins

The present disclosure relates to a zeolite based catalyst composition comprising i. at least one rare earth metal, ii. at least one zeolite, and iii. optionally, at least one promoter; wherein, said rare earth metal is impregnated in said zeolite. The amount of said rare earth metal in said composition is in the range of 0.1 to 20 w/w %. The present disclosure also relates to a process for preparing a catalyst composition. Further, the present disclosure relates to a process for reducing olefin content in a hydrocarbon stream using the catalyst of the present disclosure.

Zeolite based catalyst composition for the reduction of olefins in FCC naphtha

The present disclosure relates to a catalyst composition comprising (a) at least one rare earth metal, (b) at least one zeolite, and (c) at least one diluent, wherein, said rare earth metal is impregnated in at least one of (b) and (c); the ratio of said zeolite to said diluent ranges from 1:9 to 9:1; and the amount of said rare earth metal is in the range of 0.1 to 20 w/w %. The present disclosure also relates to a process for preparing a catalyst composition. Further, the present disclosure relates to a process for reducing the olefin content in a hydrocarbon stream using the catalyst of the present disclosure.
