Abstract
A fluid catalytic cracking (FCC) process and apparatus containing a reactor riser zone and radially extending sidearms as the first catalyst-hydrocarbon product separation means. Hydrocarbon products separated in the sidearms are conducted through an enclosed passageway to a secondary separation means, such as a cyclone. The catalyst is also conducted through the enclosed passageway to a stripping apparatus, wherein entrained hydrocarbons are removed therefrom. The enclosed passageway contains a means for accommodating sudden surges of catalyst flow and increased pressure, e.g., a trickle valve.
