Abstract:
1. A process for the production of synthesis gas comprising steps: providing a reactor system comprising: feeding a hydrocarbon gas through said hydrocarbon gas inlet to one catalytic partial oxidation zone, wherein the hydrocarbon gas has a hydrocarbon gas inlet temperature less than 400° C.; feeding an oxygen-containing gas through said plurality of oxidant gas inlets to the multitude of catalytic partial oxidation zones; and converting the hydrocarbon gas and oxygen in the multitude of catalytic partial oxidation zones to form a multitude of gas effluents comprising hydrogen and carbon monoxide; wherein at least one gas effluent gas has a gas temperature which is at least 550° C. greater than the hydrocarbon gas inlet temperature; wherein each gas effluent has a gas temperature less than 1300° C.; wherein unconverted hydrocarbon gas from one gas effluent of one catalytic partial oxidation zone is fed to the catalytic partial oxidation zone immediate downstream of said catalytic partial oxidation zone; and further wherein the gas effluent temperature of at least one catalytic partial oxidation zone is controlled by a method comprising these steps: a. measuring the gas effluent temperature of the at least one catalytic partial oxidation zone; b. comparing the measured gas effluent temperature to a desirable gas effluent temperature setpoint equal to or lower than 1300° C.; c. adjusting the O
