Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
157 words
IN THE PROCESS WHEREIN A STEAM-SENSITIVE SOLID CATALYST CONTAMINATED WITH HYDROCARBON AND OTHER CARBONACEOUS DEPOSIT IS REMOVED FROM A REACTION ZONE TO BE REHEATED AND REGENERATED BEFORE BEING RETURNED TO THE REACTION ZONE; SAID CATALYST IS PASSED TO A REGENERATION ZONE WHERE IT IS HEATED AND REGENERATED BY BURNING IN CONTACT THEREWITH A HYDROCARBON-CONTAINING FUEL GAS WITH O2 CONTAINING GAS IN EXCESS OF THE AMOUNT REQUIRED TO BURN SAID FUEL GAS, THEREBY BURNING SAID DEPOSIT FROM SAID CATALYST AND FORMING STEAM IN SAID REGENERATION ZONE; AND THE REGENERATED HOT CATALYST CONTAINING STEAM IS PASSED FROM SAID REGENERATION ZONE TO SAID REACTION ZONE, THE IMPROVEMENT COMPRISING STRIPPING SAID HOT CATALYST OF STEAM BY CONTACTING SAME WITH AT LEAST A PORTION OF SAID FUEL GAS FREE OF MOISTURE, AND AT ELEVATED TEMPERATURE, THEN PASSING THE RESULTING FUEL GAS INTO SAID REGENERATOR AS FUEL, WHEREBY SAID REGENERATED CATALYST IS SUBSTANTIALLY MOISTUREFREE; AND PASSING RESULTING MOISTURE-FREE CATALYST INTO SAID REACTION ZONE.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
134 words
A PROCESS FOR REGENERATING AND CONDITIONING A STEAM SENSITIVE PARTICULATE OXIDIZABLE METAL OXIDE CATALYST CONTAMINATED WITH CARBONACEOUS DEPOSIT FOR RETURN TO A CATALYTIC HYDROCARBON CONVERSION REACTION, WHICH COMPRISES TRANSPORTING A SUSPENSION OF SAID CATALYST IN CO2 SUBSTANTIALLY FREE OF O2 INTO A REGENERATION ZONE; MAINTAINING A FLUIDIZED DENSE BED OF SAID CATALYST IN SAID ZONE; BURNING A STREAM OF MOISTURE-FREE FUEL GAS WITH STOICHIOMETRIC AMOUNT OF AIR SEPARATELY INTRODUCED TO A CENTRAL AREA OF SAID BED TO MAINTAIN AN ELEVATED TEMPERATURE THEREIN SUFFICIENT TO REACT SAID CO2 WITH SAID DEPOSIT TO FORM CO; WITHDRAWING A STREAM OF REGENERATED CATALYST FROM SAID ZONE; AND FEEDING SAID FUEL GAS INTO SAID CENTRAL AREA OF SAID BED COUNTERCURRENTLY THRU THE EFFLUENT STREAM OF REGENERATED CATALYST TO STRIP SAME OF STEAM AND TO PROVIDE A MOISTURE FREE-REGENERATED CATALYST.
