Abstract:
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.
Abstract:
The invention relates to a method for performing endothermic process, characterized in that the annual average total energy required for the endothermic process originates from at least two different energy sources. One of the energy sources is an electrical energy source, the power of which varies between 0 and 100% of the required total power, and three different energy modes individually can provide the total required power for the endothermic process: (i) exclusively electrical energy, (ii) a mixture of electrical energy and at least one additional non-energy source, or (iii) exclusively non-electrical energy. The transition time in which the change from one energy mode to another energy mode is completed 30 minutes at most.
Abstract:
The invention relates to a device (10) for producing acetylenes and synthesis gas by partially oxidizing hydrocarbons with oxygen, comprising a reactor (12). Said reactor (12) comprises a burner block (14) with a combustion chamber for producing acetylenes, a secondary chamber (18) which is embodied in the burner block (14) and an annular space (20) which surrounds the secondary chamber (18). Said burner block (14) comprises bores (22) for feeding a flow of a hydrocarbon and oxygen mixture to the combustion chamber and bores (24) for feeding a flow of auxiliary oxygen to the combustion chamber. Said bores (24) for supplying a flow of auxiliary oxygen to the combustion chamber are connected to the secondary chamber (18). Said secondary chamber (18) is connected to the annular space (20). The invention also relates to a method for producing acetylene and synthesis gas by partially oxidizing hydrocarbons with oxygen.
Abstract:
Process for the production of synthesis gas (3), in which methane and carbon dioxide (2) are introduced into a reaction space (R) and reacted in the presence of a solid (W) at elevated temperatures to give hydrogen and carbon monoxide. Methane and carbon dioxide are passed through a carbon-containing granular material (W) and reacted in a high-temperature zone (H).
