The method may further involve introducing an oxygen-containing gas in a second reaction zone, and using the oxygen-containing gas and some hydrogen from the first reaction zone to produce thermal energy. Still further, the method may involve supplying the thermal energy produced in the second reaction zone to the first reaction zone. ## Claims ### Claim 1 A method for producing synthesis gas with a reactor comprising a first reaction zone and a second reaction zone, the method comprising: introducing, into the first reaction zone, the first reaction zone being free of a catalyst, a coke-oven gas comprising a hydrocarbon and a converter gas comprising carbon dioxide; reacting, the hydrocarbon with the carbon dioxide to form water; reacting the water, thermally with the hydrocarbon to form synthesis gas containing carbon monoxide and hydrogen; introducing, into the second reaction zone, an oxygen-containing gas and the hydrogen from the first reaction zone; producing thermal energy from the oxygen-containing gas and the hydrogen from the first reaction zone; and supplying the thermal energy produced in the second reaction zone to the first reaction zone. ### Claim 2 (depends on 1) The method of claim 1 comprising moving fixed bed comprising a granular solid from the second reaction zone to the first reaction zone. ### Claim 3 (depends on 2) The method of claim 2 comprising recycling the granular solid. ### Claim 4 (depends on 2) The method of claim 2 comprising: running the synthesis gas through the second reaction zone counter-current to the moving fixed bed and thus cooling the synthesis gas by passing the synthesis gas over the granular solid of the moving fixed bed; and running the coke oven gas and the converter gas counter-current to the moving fixed bed in the first reaction zone and thus heating the coke oven gas and the converter gas by passing the coke oven gas and the converter gas over the granular solid of the moving fixed bed. ### Claim 5 (depends on 2) The method of claim 2 comprising depositing carbon on the granular solid during said producing of thermal energy step, separating the deposited carbon from the granular solid, and removing the separated carbon from the moving fixed bed downstream of the first reaction zone. ### Claim 6 (depends on 2) The method of claim 2 wherein the granular solid is one or more of corundum (Al2O3), quartz glass (SiO2), mullite (Al2O3.SiO2), cordierite ((Mg,Fe)2(Al2Si)[Al2Si4O18]), steatite (SiO2.MgO.Al2O3), coal, coke, or produced by thermal decomposition of the hydrocarbon. ### Claim 7 (depends on 1) The method of claim 1 further comprising supplying water or steam to the first reaction zone. ### Claim 8 (depends on 1) The method of claim 1 wherein the coke-oven gas comprises methane. ### Claim 9 (depends on 8) The method of claim 8 wherein the converter gas is produced from operation of a steelworks. ### Claim 10 (depends on 1) The method of claim 1 wherein the converter gas is produced from operation of a steelworks. ### Claim 11 (depends on 1) The method of claim 1 comprising adding additional hydrocarbons to the first reaction zone to set a hydrogen to carbon monoxide ratio in the synthesis gas at an output of the reactor between 0.8 and 2.5. ### Claim 12 (depends on 1) The method of claim 1 comprising adding methane to the first reaction zone to set a hydrogen to carbon monoxide ratio in the synthesis gas at an output of the reactor between 0.8 and 2.5. ### Claim 13 (depends on 1) The method of claim 1 comprising adding natural gas to the first reaction zone to set a hydrogen to carbon monoxide ratio in the synthesis gas at an output of the reactor between 0.8 and 2.5. ### Claim 14 (depends on 1) The method of claim 1 wherein the thermal energy in the second reaction zone is produced at least partially by electric current. ### Claim 15 (depends on 1) The method of claim 1 wherein the granular solid is one or more of corundum (Al2O3), quartz glass (SiO2), mullite (Al2O3.SiO2), cordierite ((Mg,Fe)2(Al2Si)[Al2Si4O18]), steatite (SiO2.MgO.Al2O3), coal, coke, or produced by thermal decomposition of the hydrocarbon.
