Production of hydrogen and carbon monoxide

Claim 1

A METHOD FOR PRODUCING A HYDROGEN STREAM AND A CARBON MONOXIDE STREAM WHICH COMPRISES FEEDING A HYDROCARBON INTO A REACTION ZONE CONTAINING A FLUIDIZED DEHYDROGENATION CATALYST AT A TEMPERATURE WITHIN THE RANGE FROM ABOUT 1300* TO ABOUT 2400*F. UNDER CONDITIONS TO DEPOSIT FROM ABOUT 0.1% TO ABOUT 10% BY WEIGHT OF CARBON ON SAID CATALYST AND TO FORM A PRODUCT CONTAINING SUBSTANTIAL AMOUNTS OF HYDROGEN, SEPARATING SAID PRODUCT FROM THE CARBON-CONTAINING CATALYST, CONTACTING SAID CARBON-CONTAINING CATALYST WITH SUBSTANTIALLY PURE OXYGEN AT A TEMPERATURE WITHIN THE RANGE FROM ABOUT 1400* TO ABOUT 2500*F. UNDER CONDITIONS TO FORM A SECOND PRODUCT IN ADMIXTURE WITH SUBSTANTIALLY CARBON-FREE CATALYST CONTAINING SUBSTANTIAL AMOUNTS OF CARBON MONOXIDE, COOLING SAID ADMIXTURE IN A COOLING ZONE TO A TEMPERATURE WITHIN THE RANGE FROM ABOUT 500* TO ABOUT 700*F., INTRODUCING THE COOLED ADMIXTURE INTO A SEPARATION ZONE AND THERE SEPARATING CATALYST FROM SAID SECOND PRODUCT, AND SEPARATELY RECOVERING SAID HYDROGEN AND CARBON MONOXIDECONTAINING PRODUCTS, SAID ADMIXTURE BEING QUENCHED TO A TEMPERATURE WITHIN THE RANGE FROM ABOUT 600* TO BELOW ABOUT 900*F. PRIOR TO COOLING BY ADDING TO SAID ADMIXTURE A PORTION OF THE COOLED CATALYST, SAID COOLING AND SEPARATION ZONES HAVING EXPOSED METALLIC SURFACES.

Claim 2

A METHOD FOR PRODUCING A HYDROGEN STREAM AND A CARBON MONOXIDE STREAM WHICH COMPRISES FEEDING A HYDROCARBON INTO A REACTION ZONE CONTAINING A FLUIDIZED DEHYDROGENATION CATALYST AT A TEMPERATURE WITHIN THE RANGE FROM ABOUT 1300* TO ABOUT 2400*F. UNDER CONDITIONS TO DEPOSIT FROM ABOUT 0.1% TO ABOUT 10% BY WEIGHT OF CARBON ON SAID CATALYST AND TO FORM A PRODUCT CONTAINING SUBSTANTIAL AMOUNTS OF HYDROGEN, SEPARATING SAID PRODUCT FROM THE CARBON-CONTAINING CATALYST, CONTACTING SAID CARBON-CONTAINING CATALYST WITH SUBSTANTIALLY PURE OXYGEN AT A TEMPERATURE WITHIN THE RANGE FROM ABOUT 1400* TO ABOUT 2500*F. UNDER CONDITIONS TO FORM A SECOND PRODUCT IN ADMIXTURE WITH SUBSTANTIALLY CARBON-FREE CATALYST CONTAINING SUBSTANTIAL AMOUNTS OF CARBON MONOXIDE, COOLING SAID ADMIXTURE IN A COOLING ZONE TO A TEMPERATURE WITHIN THE RANGE FROM ABOUT 500* TO ABOUT 700*F., INTRODUCING THE COOLED ADMIXTURE INTO A SEPARATION ZONE AND THERE SEPARATING CATALYST FROM SAID SECOND PRODUCT, AND SEPARATELY RECOVERING SAID HYDROGEN AND CARBON MONOXIDECONTAINING PRODUCTS, SAID ADMIXTURE BEING QUENCHED TO A TEMPERATURE WITHIN THE RANGE FROM ABOUT 600* TO BELOW ABOUT 900*F. PRIOR TO COOLING BY ADDING TO SAID ADMIXTURE A PORTION OF THE COOLED CATALYST, SAID COOLING AND SEPARATION ZONES HAVING EXPOSED METALLIC SURFACES.
