Claim 3
Dependent Claim
102 words
IN A PROCESS FOR CARRYING OUT A CATALYTIC REACTION WITH AN UPFLOWING REACTANT STREAM CONTAINING A HYDROCARBON VAPOR AND FINELY DIVIDED CATALYST PARTICLES, THE STEPS COMPRISING DIVIDING THE REACTANT STREAM SOMEWHAT UNIFORMLY ACROSS ITS FLOW AREA INTO A PLURALITY OF ADJACENT PARALLEL SMALLER STREAMS, CONDUCTING THE SMALLER STREAMS UPWARDLY AND SEPARATELY SO THAT AN INNER STREAM IN EMBRACED BY AN OUTER STREAM, AND SUBSEQUENTLY MERGING SAID STREAMS, THE IMPROVEMENT COMPRISING INCREASING THE VELOCITY OF AN INNER SMALLER STREAM AT THE POINT OF MERGING IT WITH THE NEXT ADJACENT OTHER STREAM TO INSPIRATE THE LATTER AND THEREBY PREVENT BACK-MIXING OF ENTRAINED CATALYST PARTICLES.
