Patent
·
OSTI ID:5921925
An apparatus is described for mixing fluid catalytic cracking catalyst and hydrocarbon feedstock comprising: an enclosed chamber having an outlet end; an elongated tubular riser having an upstream end and a downstream end the upstream end being arranged in fluid communication with the outlet end of the chamber; a catalyst inlet conduit attached to and in fluid communication with the interior of the enclosed chamber; a first vertical conduit for introducing lift gas into the interior of the enclosed chamber, the first conduit having an upstream end and a downstream end; a second vertical conduit having a upstream end and a downstream end, the second conduit upstream end being within the enclosed chamber, the second conduit downstream end being in fluid communication with the riser, the second conduit being axially aligned with the riser and the first conduit; and means for passing the hydrocarbon feedstock in atomized form in annular flow from the outlet end of the enclosed chamber into the riser upstream end.
