摘要:
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 hydrogen, contained in the hydrocarbon-containing coke-oven gas (2), is at least partially reacted with carbon dioxide in order to form water and the water is thermally reacted with the hydrocarbon in order to produce synthesis gas, which contains carbon monoxide and hydrogen. In a second reaction zone (Z2), an oxygen-containing gas (3) is introduced and thermal energy is produced by means of said oxygen-containing gas and part of the hydrogen from the first reaction zone (Z1), wherein the thermal energy produced in the second reaction zone (Z2) is supplied to the first reaction zone (Z1).
摘要:
The invention relates to a process for utilizing a hydrocarbon-containing and/or carbon dioxide-containing blast furnace gas, accompanying gas and/or biogas, characterized in that hydrocarbon-containing and/or carbon dioxide-containing blast furnace gas, accompanying gas and/or biogas is introduced into a reaction chamber, and the multicomponent mixture present in the blast furnace gas, accompanying gas and/or biogas is converted in a high-temperature zone at temperatures of above 1000°C and in the presence of a support into a product-gas mixture which consists of more than 95% by volume CO, CO 2 , H 2 , H 2 O, CH 4 and N 2 , and optionally into a carbon-containing solid of which more than 75% by weight, based on the total mass of the carbon-containing solid, is deposited onto the support, wherein the flow velocity of the gas mixture blast furnace gas, accompanying gas and/or biogas in the reaction zone is less than 20 m/s.
