<p>A process wherein a feedstock is subjected to an endothermic reaction, particularly a catalytic reaction, and particularly a process for reforming a feed comprising a gaseous mixture of hydrocarbons and steam which is passed at an elevated pressure over a catalyst to produce reformed gas containing hydrogen and carbon oxides, the heat required for the endothermic reaction being supplied by heat exchange with a flow of hot combustion products generated by burning a fuel in a pressurized oxidant flow in a combustion zone thereby particularly cooling said flow of combustion products, and thereafter recirculating part of the partially-cooled flow of combustion products by adding said part to said pressurized oxidant flow before said oxidant flow enters said combustion zone; and apparatus therefor.</p> |
