Abstract

High-severity fluid catalytic cracking (HS-FCC) is a new process for the conversion of heavy oils into lighter hydrocarbon products and petrochemical feedstocks. Research teams from Japan and Saudi Arabia are jointly developing this technology. The process combines mechanical modifications to conventional FCC with changes in process variables and catalyst formulations. The main operating regime of the process is a special down-flow reactor system, high reaction temperature, short contact time, and high catalyst/oil ratio. Experimental runs were conducted in a downer and riser-type pilot plants (capacity 0.1 BPD) and a demonstration plant (capacity 30BPD) using various catalysts, additives, and feed oils. Pilot plant results demonstrated the advantage of downer in suppressing back-mixing, thus increasing the yield of light olefins and reducing dry gas. Using paraffinic crude base vacuum gas oil (VGO), propylene yield of 25wt% was obtained under HS-FCC reaction conditions.
