Patent ID: 8323477

Claim:
A process for contacting regenerated catalyst with a hydrocarbon feed, said process comprising: urging said regenerated catalyst upwardly in a reactor riser with fluidizing gas; contacting said hydrocarbon feed with said regenerated catalyst in said reactor riser to crack said hydrocarbon feed to produce lighter gaseous hydrocarbons and deposit coke on the catalyst to produce carbonized catalyst; separating said gaseous hydrocarbons from said carbonized catalyst; contacting at least a portion of said carbonized catalyst with oxygen to combust coke from said catalyst to produce regenerated catalyst; passing said regenerated catalyst to said riser in a regenerated catalyst conduit; and obstructing partially upward flow of said regenerated catalyst in said riser by a baffle in said riser below said feed distributor and proximate to an intersection between said regenerated catalyst conduit and said riser to mix said regenerated catalyst in said riser before contacting said hydrocarbon feed.
