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 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).
Abstract:
The invention relates to a device (10) for producing acetylene and synthesis gas by partially oxidizing hydrocarbons by means of oxygen. The device (10) comprises a reactor (12), wherein the reactor (12) has a burner block (14) having a combustion chamber for producing a composition Z1 containing at least acetylene and substituted acetylene, a first scrubber (22), which is designed to mix the composition Z1 with a solvent, a composition Z2 thus being obtained, a second scrubber (26), which is designed to mix the composition Z2 with the solvent, a composition Z3 thus being obtained, a first stripper (36), which is designed to strip the composition Z3, a composition Z4 containing the substituted acetylene, acetylene, and the solvent thus being obtained, and to separate the acetylene, a first column (46), which is designed to partially degas the composition Z4 at a pressure of 1.0 bar to 1.5, a composition Z5 and a first portion A1 of the solvent thus being obtained, a second stripper (56), to which the composition Z5 can be fed for stripping a composition Z9, a second portion A2 of the solvent and a composition Z6 thus being obtained, a third stripper (68), which is designed to strip the solvent from the first scrubber (22), a composition Z9 thus being obtained, a third stripper (68), which is designed to strip the solvent from the first scrubber (22), a composition Z9 thus being obtained, wherein the third stripper (68) is connected to the second stripper (56) in order to feed the composition Z9 to the second stripper (56), a device (72) for mixing the composition Z5 with a thinning gas, which device is arranged between the first column (46) and the second stripper (56), a second column (76), which is designed to mix the composition Z6 with water, a composition Z7 containing a third portion A3 of the solvent and water thus being obtained and a composition Z8 containing the substituted acetylene thus being obtained, and a direct-contact condenser (82), which is designed to mix the composition Z8 with water, a composition Z11 containing the substituted acetylene thus being obtained. The invention further relates to a method for producing acetylene and synthesis gas by partially oxidizing hydrocarbons by means of oxygen.
