The configuration of HS-FCC includes a downer-reactor system operating at high reaction temperatures, higher catalyst/oil ratios and short contact time. This configuration prevents back-mixing and suppresses thermal cracking reactions thereby maximizing gasoline and light olefins. The performance of a downer-type reactor versus riser has been studied in a pilot plant with a capacity of 0.2 b/d. At 80wt% conversion, the downer system showed 22% increase in the production of gasoline compared to the riser system. The production of C2-C4 light olefins in the downer was relatively high at 23wt% but lower than the riser due to gasoline over-cracking in the riser. Yields of dry gas, coke, and 1,3 butadiene in the downer reactor were much lower compared to the riser reactor. The results confirmed reduced effects of thermal cracking and back-mixing in the downer system configuration.
