Abstract: 753,051. Oil gas generation. SOC. DE CONSTRUCTION D'APPAREILS POURGAZ A L'EAU & GAZ INDUSTRIELS. April 2, 1954 [April 9, 1953], No. 9813/54. Drawings to Specification. Class 55(2). In a cyclic process of gas manufacture comprising the cracking of fluid hydrocarbons mixed or not with steam or oxidizing media in one stage by contact with a refractory or catalyst mass and heating up the plant in a second stage, oxygen-containing heating. gases for burning away carbon deposits in this stage are heated by heat recovery from heating gases of lower or no oxygen content produced in the same stage. The gaseous flow in each chamber of the plant is always in the same direction. In one example, hot combustion products from an oil burner in one chamber pass first through a heat storage chamber and then the gas making chamber during part of the heating stage, and for the rest of it air is passed through all the chambers and the oil supply to the burner advanced or stopped. Or the change in oxygen content of the gases may be effected gradually and continuously. In a modification in the initial part of the stage the combustion products are not passed through the gas making chamber. In another arrangement air for the heating stage is preheated by heat exchange with the products of carbon burning leaving the gas making chamber. Additional heat may be supplied by fuel combustion at a suitable part of the circuit. Specification 751,510 is referred to.
