The present invention relates to a catalyst additive composition suitable for fluid cracking, riser cracking and fixed bed cracking with reduction in bottom and coke, wherein the aluminosilicate and silica-alumina is generated in situ from added clay and silica. The present invention is also directed towards the preparation of the said catalyst additive composition. The invention also discloses a process for cracking of heavy hydrocarbons using the said catalyst additive.

Catalyst additive composition for catalytic cracking and a process of preparation thereof

Disclosed herein is an improved fluidized catalytic cracking process for converting normally liquid hydrocarbon feedstock with simultaneous reduction of sulfur content in the liquid products obtained therefrom which comprises carrying out the cracking process in the presence of carbon monoxide gas as a reducing agent. The process optionally includes a step of premixing the hydrocarbon feedstock with carbon monoxide gas causing major sulfur reduction before effecting the cracking. The premixing is done in a specified nozzle assembly linked to the FCC unit.
