Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
142 words
IN THE CONTINUOUS PROCESS FOR THE PRODUCTION OF HYDROGEN AND CARBON OXIDES BY REFORMING HYDROCARBONS OF HIGHER MOLECULAR WEIGHT THAN METHANE BY PASSING SAID HYDROCARBONS MIXED WITH AN OXYGEN-CONTAINING GAS OVER AN EXTERNALLY HEATED REFORMING CATALYST MAINTAINED AT A REFORMING TEMPERATURE WITHIN THE RANGE OF 1200* TO 2000* F., THERE BEING PRESENT SUFFICIENT OXYGEN-CONTAINING GAS TO CONVERT SUBSTANTIALLY ALL OF THE HYDROCARBONS INTO HYDROGEN AND CARBON OXIDES, THE IMPROVEMENT OF ADVANTAGEOUSLY INHIBITING SIGNIFICANT CRACKING OF SAID HYDORCARBONS WITH ATTENDANT DEPOSITION OF CARBON ON SAID REFORMING CATALYST, COMPRISING THE STEP OF: RAIDING THE TEMPERATURE OF THE REACTANT GASES TO THE REFORMING TEMPERATURE PRIOR TO THEIR CONTACT WITH THE HEATED REFORMING CATALYST BY PASSING SAID GASES OVER AN EXTERNALLY HEATED MASS OF PREHEATED MATERIAL COMPRISING ALUMINA AND WHICH IS FREE OF IRON AND NICKEL, SAID PREHEAT MATERIAL BEING SUBSTANTIALLY DEVIOD OF CATALYTIC REFORMING ACTIVITY.
