ABSTRACT:
Process and apparatus for hydrocarbon conversion, such as, fluid catalytic cracking, in which finely divided catalyst is circulated from a catalyst regeneration vessel through a standpipe connected by an angle bend to a vertically inclined conduit which in turn is connected to a straight vertical transferline riser reaction zone into a gas-solids disengaging and stripping vessel without the necessity of a variable orifice flow control valve. Separated spent and stripped catalyst flows from the disengaging-stripping vessel to the regeneration vessel through an external conduit.
