Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
126 words
A PROCESS FOR THE PYROLYSIS OF HYDROCARBON REACTANTS TO PRODUCE UNSATURATED HYDROCARBONS HAVING A HIGHER CARBON-TO-HYDROGEN RATIO WHICH COMPRISES: PREHEATING HYDROCARBON REACTANTS AND PRODUCING A GASEOUS STREAM THEREOF; ADMITTING SAID STREAM AT A TEMPERATURE OF AT LEAST 700*C. WITH VORTICAL MOTION INTO A CONFINED, ELONGATED VORTEX ZONE TO FORM A GAS-VORTEX AND THEREIN TRANSFERRING HEAT BY THE HEAT-SEPARATION EFFECT FROM THE PART OF SAID ADMITTED GAS AT THE VORTEX CORE TO THE PART OF SAID ADMITTED GAS AT THE VORTEX PERIPHERY, THEREBY HEATING THE LATTER GAS TO PYROLYSIS TEMPERATURE AND DEHYDROGENATING SAID HYDROCARBON REACTANTS SAID PREHEATING AND HEATING IN THE VORTEX ZONE BEING EFFECTED ESSENTIALY IN THE ABSENCE OF OXYGEN AND OXYGENATED DISSOCIATION PRODUCTS; AND CONTINUOUSLY DISCHARGING GAS INCLUDING DEHYDROGENATION REACTION PRODUCTS FROM SAID VORTEX ZONE.

Claim 3
Dependent Claim
118 words
A VORTEX-TUBE REACTOR COMPRISING AN ELONGATED TUBE HAVING AN INTERIOR SURFACE OF REVOLUTION FORMED BY REFRACTORY MATERIAL; INLET MEANS INCLUDING AN OUTER, REFRACTORY-LINED FEED CHAMBER, AN INNER SWIRL CHAMBER IN FREE COMMUNICATION WITH SAID TUBE, AND INLET PORT MEANS FOR FEEDING REACTANT GAS FROM SAID FEED CHAMBER TANGENTIALLY INTO SAID SWIRL CHAMBER TO FORM A GAS-VORTEX; A WALL ADJOINING THE SIDE OF THE SWIRL CHAMBER OPPOSITE TO SAID TUBE, SAID WALL HAVING THEREIN A CENTRAL ORIFICE FOR DISCHARGING GAS FROM THE CORE OF SAID VORTEX; A HOT-GAS OUTLET FOR DISCHARGING REACTED GAS FROM THE PERIPHERY OF SAID GAS-VORTEX; AND QUENCHING MEANS FOR INJECTING A QUENCH FLUID INTO THE LATTER GAS AT A POINT REMOTE FROM THE SWIRL CHAMBER.
