Method of effecting chemical conversions

Claim 1

THE METHOD OF CONDUCTING AN ENDOTHERMIC CHEMICAL REACTION IN THE PRESENCE OF A SOLID CATALYST IN POWDERED CONDITION AT A HIGH TEMPERATURE WITH A SHORT CONTACT TIME BETWEEN REACTION MATERIAL AND CATALYST WHICH COMPRISES ESTABLISHING AN ELEVATED RESERVIOR OF HOT POWDERED CATALYST, ESTABLISHING A REACTION ZONE AT A SUBSTANTIALLY LOWER LEVEL, ESTABLISHING A COLUMN OF HOT POWDERED CATALYST IN FLUIDIZED CONDITION BETWEEN SAID RESERVIOR AND SAID REACTION ZONE, PROVIDING FOR A CONTINUOUS OPEN FLOW OF CATALYST FROM THE BOTTOM OF SAID COLUMN INTO SAID REACTION ZONE, ADMIXING WITH CATALYST LEAVING SAID COLUMN A GASEOUS REACTANT, CAUSING SAID GASEOUS REACTANT, TO FLOW AT A SUFFICIENTLY HIGH VELOCITY TO CARRY SAID HOT POWDERED CATALYST THROUGH SAID REACTION ZONE CONCURRENTLY WITH SAID REACTANT AND AT SUBSTANTIALLY THE SAME VELOCITY TO WHERE THE CATALYST WITH GASEOUS PRODUCTS OF REACTION ARE DISCHARGED FROM THE REACTION ZONE AT ITS OUTLET, SAID VELOCITY BEING PRESELECTED TO PROVIDE THE DESIRED SHORT CONTACT TIME BETWEEN CATALYST AND REACTANT, ABRUPTLY SEPARATING SAID POWDERED CATALYST FROM GASEOUS PRODUCTS OF REACTION AT THE OUTLET OF SAID REATION ZONE, QUENCHING THE PRODUCTS OF REACTION AT THE POINT OF SEPARATION THEREOF FROM SAID CATALYST AND CONTROLLING THE TEMPERATURE OF SAID REACTION ZONE BY CONTROLLING THE TEMPERATURE AND THE STATIC HEAD OF SAID FLUIDIZED SOLIDS FLOWING FROM THE BOTTOM OF SAID COLUMN INTO SAID REACTION ZONE.

Claim 2

THE METHOD OF CONDUCTING AN ENDOTHERMIC CHEMICAL REACTION IN THE PRESENCE OF A SOLID CATALYST IN POWDERED CONDITION AT A HIGH TEMPERATURE WITH A SHORT CONTACT TIME BETWEEN REACTION MATERIAL AND CATALYST WHICH COMPRISES ESTABLISHING AN ELEVATED RESERVIOR OF HOT POWDERED CATALYST, ESTABLISHING A REACTION ZONE AT A SUBSTANTIALLY LOWER LEVEL, ESTABLISHING A COLUMN OF HOT POWDERED CATALYST IN FLUIDIZED CONDITION BETWEEN SAID RESERVIOR AND SAID REACTION ZONE, PROVIDING FOR A CONTINUOUS OPEN FLOW OF CATALYST FROM THE BOTTOM OF SAID COLUMN INTO SAID REACTION ZONE, ADMIXING WITH CATALYST LEAVING SAID COLUMN A GASEOUS REACTANT, CAUSING SAID GASEOUS REACTANT, TO FLOW AT A SUFFICIENTLY HIGH VELOCITY TO CARRY SAID HOT POWDERED CATALYST THROUGH SAID REACTION ZONE CONCURRENTLY WITH SAID REACTANT AND AT SUBSTANTIALLY THE SAME VELOCITY TO WHERE THE CATALYST WITH GASEOUS PRODUCTS OF REACTION ARE DISCHARGED FROM THE REACTION ZONE AT ITS OUTLET, SAID VELOCITY BEING PRESELECTED TO PROVIDE THE DESIRED SHORT CONTACT TIME BETWEEN CATALYST AND REACTANT, ABRUPTLY SEPARATING SAID POWDERED CATALYST FROM GASEOUS PRODUCTS OF REACTION AT THE OUTLET OF SAID REATION ZONE, QUENCHING THE PRODUCTS OF REACTION AT THE POINT OF SEPARATION THEREOF FROM SAID CATALYST AND CONTROLLING THE TEMPERATURE OF SAID REACTION ZONE BY CONTROLLING THE TEMPERATURE AND THE STATIC HEAD OF SAID FLUIDIZED SOLIDS FLOWING FROM THE BOTTOM OF SAID COLUMN INTO SAID REACTION ZONE.
