The disclosure relates to an anti fouling composition including a metallic component comprising of at least one alkali metal salt and a non-metallic component and method for preparation of anti fouling composition. The disclosure also relates to a process of reducing fouling in reactors or furnaces using said composition.

Descaling and anti fouling composition

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

The present disclosure relates to a catalyst for slurry phase hydrocracking of refinery residue and a process for its preparation. The present disclosure provides a very simple method for exfoliation of metal sulphide, and a process of that provides effective slurry phase hydrocracking of refinery residue with a high yield.
