Claim 1
Independent Claim
141 words
A METHOD FOR THE CATALYTIC REFORMING UNDER PRESSURE OF HYDROCARBONS FOR OBTAINING HYDROGBEN-CARBON MONOXIDE MIXTURES, COMPRISING FORMING A MIXTGURE OF GASIFORM HYDROCARBONS WITH AN OXIDIZING GAS INCLUDING AT LEAST ONE GAS OF THE GROUP CONSISTING OF STEAM AND CARBON DIOXIDE, CONSTRAINING SAID MIXTURE TO FLOW UPWARDLY INSIDE A PLURALITY OF VERTICAL TUBES OVER A CATALYST FOR THE REFORMING REACTION, BURNING FUEL AT SEVERAL SUCCESSIVE LEVELS NEAR SAID TUBES TO FORM A STREAM OF HOT COMBUSTION GASES FLOWING AROUND SAID TUBES IN THE SAME DIRECTION AS SAID MIXTURE PASSING OVER THE CATALYST AND IN INDIRECT HEAT-EXCHANGE RELATIONSHIP WITH SAID MIXTURE TO REFORM THE LATTER AND ADJUSTING THE HEAT INPUTS OF SAID COMBUSTION GASES FOR MAINTAINING THE TEMPERATURE OF THE OUTSIDE SURFACE OF SAID TUBES AT A SUBSTANTIALLY CONSTANT VALUE OVER THE ENTIRE LENGTH THEREOF IN WHICH THE CATALYTIC REFORMING IS BEING EXECUTED.
