Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
140 words
THE PROCESS OF CONVERTING A HEAVY HYDROCARBON OIL OF HIGH RAMSBOTTOM CARBON RESIDUE WHICH COMPRISES CONVERTING SAID OIL AT AN ELEVATED TEMPERATURE IN A CRACKING ZONE IN THE PRESENCE OF A HYDROGEN-CONTAINING ATMOSPHERE AND PARTICULATE CONTACT MATERIAL ON WHICH A CARBONACEOUS DEPOSIT IS FORMED BY SAID OIL UNDERGOING CONVERSION, GASFYING A PORTION OF SAID CARBONACEOUS DEPOSIT IN ONE REGENERATION ZONE WITH STEAM AND HIGH-PURITY OXYGEN AT A TEMPERATURE OF AT LEAST 1600*F. THEREBY FORMING REGENERATION PRODUCT GASES CONTAINING HYDROGEN, FLOWING ALL OF SAID REGENERATION PRODUCT GASES THROUGH SAID CRACKING ZONE TO PROVIDE THEREIN SAID HYDROGEN-CONTAINING ATMOSPHERE, GASIFYING ANOTHER PORTION OF SAID CARBONACEOUS DEPOSIT WITH AIR IN ANOTHER REGENERATION ZONE, WITHDRAWING ALL OF THE RESULTING GASEOUS RPODUCT EFFLUENT FROM SAID OTHER REGENERATION ZONE SEPARATE FROM SAID REGENERATION PRODUCT GASES, AND CIRCULATING SAID CONTACT MATERIAL THROUGH SAID CRACKING AND TWO REGENERATION ZONES.
