1. A process for recovering catalyst from a fluidized catalytic reactor effluent comprising:
reacting a reactant stream by contact with a stream of fluidized catalyst to provide a vaporous reactor effluent stream comprising catalyst and products;
contacting said vaporous reactor effluent stream with a liquid coolant stream in a contact cooler, wherein said vaporous reactor effluent stream is passed to a top of said contact cooler;
cooling said vaporous reactor effluent stream;
transferring said catalyst into said liquid coolant stream;
separating a catalyst lean vaporous reactor effluent stream from a catalyst rich liquid coolant stream;
separating a return catalyst stream from said catalyst rich liquid coolant stream to provide a catalyst lean liquid coolant stream; and
transporting said return catalyst stream back to said reacting step.
