Claim 1
Independent Claim
164 words
A REACTOR ADAPTED FOR USE IN A PROCESS FOR THE PRODUCTION OF UNSATURATED HYDROCARBONS WHICH COMPRISES, IN COMBINATION, A FLUID INLET CONDUIT; A VENTURI COMPRISING A CONVERGING SECTION, A THROAT SECTION AND A DIVERGING SECTION, SAID CONVERGING SECTION BEING CONNECTED TO THE DOWNSTREAM END OF SAID INLET CONDUIT AND SAID THROAT SECTION ENCOMPASSING THE SOLE CONSTRICTED PASSAGE IN SAID REACTOR; A FLUID OUTLET CONDUIT HAVING ITS UPSTREAM END CONNECTEED TO SAID DIVERGING SECTION, SAID FLUID INLET CONDUIT, SAID VENTURI, AND SAID FLUID OUTLET CONDUIT FORMING A CONTINUOUS, UNOBSTRUCTED PASSAGE IN SAID REACTOR; A FLUID INTRODUCTION MEANS POSITIONED IN SAID REACTOR BE TWEEN THE DOWNSTREAM END OF SAID THROAT SECTION AND THE DOWNSTREAM END OF SAID FLUID OUTLET CONDUIT; AND FLUID INLET JETS POSITIONED IN SAID REACTOR FOR INJECTING A PLURALITY OF FLUID STREAMS INTO SAID REACTOR SO THAT SAID STREAMS IMPINGE AT ABOUT THE LONGITUDINAL AXIS OF SAID REACTOR, SAID FLUID INLET JETS BEING INCLINED TOWARD THE UPSTREAM END OF SAID FLUID INLET CONDUIT.

Claim 3
Dependent Claim
128 words
A PROCESS FOR THE PRODUCTION OF UNSATURATED HYDROCARBONS WHEREIN THE REACTANTS ARE PREHEATED GASEOUS HYDROCARBONS AND PREHEATED OXIDANT WHICH COMPRISES INTRODUCING AN AXIAL STREAM COMPRISING ONE OF SAID REACTANTS INTO ONE END OF AN ELONGATED CONDUIT; INCREASING THE VELOCITY OF SAID AXIAL STREAM IN A PORTION OF SAID CONDUIT; INJECTING A PLURALITY OF STREAMS COMPRISING THE OTHER OF SAID REACTANTS LATERALLY INTO THE ACCELERATED AXIAL STREAM SO THAT THE PLURALITY OF LATERAL STREAMS IMPINGE; RAPIDLY AND UNIFORMLY MIXING SAID REACTANTS; PARTIALLY BURNING THE RESULTING MISTURE IN A REACTION ZONE; UNTILIZING THE HEAT GIVEN UP IN THE PARTIAL OXIDATION REACTION TO CRACK THE REMAINDER OF THE HYDROCARBONS AND FORM THE DESIRED UNSATURATED HYDROCARBON; AND COOLING THE REACTION PRODUCTS TO A TEMPERATURE AT WHICH THE RESULTING UNSATURATED HYDROCARBON IS STABLE.
