Problems solved by technology
However, this technology is not suitable for coke oven gas and converter gas applications because the reverse water gas shift reaction occurs in the reactor with catalyst
However, the catalyst will only have a short lifetime due to impurities in coke and converter gases
In addition, since the reverse water gas shift reaction is carried out in separate reactors, the heat integration is not optimal

Embodiment Construction
[0030] figure 1 A preferred design of the process according to the invention is shown, wherein a reactor is used, a moving bed of granular solids passes through the reaction chamber of the reactor, the reactor comprises a first reaction zone and a second reaction zone, and a first heat exchange zone and a second heat exchange zone.
[0031] Granular solids are supplied via line 1 into reaction chamber R of reactor K at ambient temperature. Particulate solids are, for example, carbon produced in the process by thermal decomposition of hydrocarbons. The granular solids flow downward in the moving bed W due to gravity. The hydrocarbon-containing gas 2 flows from the bottom into the reaction chamber R together with the carbon dioxide-containing gas 4 and passes upwards through the moving bed W in countercurrent. The hydrocarbon-containing gas 2 and the carbon dioxide-containing gas 4 enter the reaction chamber R at ambient temperature and are heated by direct heat exchange with...

Abstract
The invention relates to a method for producing synthesis gas (5), wherein a hydrocarbon-containing coke oven gas (2) and a carbon dioxide-containing converter gas (4) are introduced into a first reaction zone (Z1) and said The hydrogen contained in the hydrocarbon-containing coke oven gas (2) is at least partially reacted with carbon dioxide to produce water, and the water is thermally reacted with the hydrocarbons to produce a synthesis gas (5) comprising carbon monoxide and hydrogen. In the second reaction zone (Z2), an oxygen-containing gas (3) is introduced and thermal energy is generated by means of the oxygen-containing gas and a part of the hydrogen from the first reaction zone (Z1), wherein the The thermal energy generated in the second reaction zone (Z2) is supplied to the first reaction zone (Z1).
Description
technical field [0001] The invention relates to a process for the production of synthesis gas, wherein a hydrocarbon-containing coke oven gas and a carbon dioxide-containing converter gas are introduced into a first reaction zone, and the hydrogen present in the hydrocarbon-containing coke oven gas is at least partially Reacts with carbon dioxide to produce water, and thermally reacts water with hydrocarbons to produce synthesis gas comprising carbon monoxide and hydrogen. Furthermore, in the second reaction zone, an oxygen-containing gas is introduced and thermal energy is generated by means of the oxygen-containing gas and a part of the hydrogen from the first reaction zone. Background technique [0002] Syngas refers to a mixture comprising hydrogen and carbon monoxide, which can be used as a base chemical in a variety of industrial processes. For example, synthesis gas is used to produce methanol, dimethyl ether or hydrocarbons. [0003] A method of conventional type i...
