ABSTRACT:
Exothermic reaction of a fluid stream is carried out with recycle and addition of hot reacted fluid to the colder feed fluid stream, so as to raise the feed fluid stream to operable reaction temperatures and produce optimum reaction rate. The addition of hot reacted fluid is carried out by reactor-internal ejector-effected aspiration of a portion of the hot reacted fluid discharged from the reaction zone into the cold feed fluid. The resulting combined fluid stream is passed to the reaction zone. The balance of the hot reacted fluid not aspirated into the cold feed fluid is passed to product recovery or utilization. The invention is especially applicable to exothermic catalytic reactions.
