摘要:
A process for producing hydrogen and pyrolytic carbon from hydrocarbons may involve converting hydrocarbons into hydrogen and carbon in a reactor at temperatures of 1000° C. or more. The reactor may include two electrodes spaced apart from one another in a flow direction of the hydrocarbons. In a region of the reactor between the electrodes an inert gas component is supplied over an entire reactor cross section. The reactor contains carbon particles in the region between the two electrodes. By introducing an inert gas component over the entire reactor cross section, deposition of carbon in this region of the reactor inner wall is prevented, thus effectively inhibiting the formation of conductivity bridges on the reactor inner wall.
摘要:
The invention relates to a process for producing synthesis gas (5) in which hydrocarbon (2) is decomposed thermally in a first reaction zone (11) to hydrogen and carbon, and hydrogen formed is passed from the first reaction zone (Z1) into a second action zone (Z2) in order to be reacted therein with carbon dioxide (4) to give water and carbon monoxide. The characteristic feature here is that energy required for the thermal decomposition of the hydrocarbon is supplied to the first reaction zone (Z1) from the second reaction zone (Z2).

The invention relates to a process for producing synthesis gas, in which carbon and hydrogen are obtained from hydrocarbon by thermal decomposition. At least a portion of the carbon obtained by the thermal decomposition is reacted, and at least a portion of the hydrogen obtained is reacted with carbon dioxide by a reverse water-gas shift reaction to give carbon monoxide and water. Carbon obtained by the thermal hydrocarbon decomposition is used as fuel in a power plant operation wherein the carbon is combusted to produce electrical power, and carbon dioxide formed in the combustion of the carbon is used in the reverse water-gas shift reaction.

The invention relates to a method of carrying out heat-consuming processes, wherein the total energy required averaged over a year for the heat-consuming process originates from at least two different energy sources, where one of the energy sources is an electric energy source whose power varies in the range from 0 to 100% of the total power required, and three different energy modes can individually provide the total power required for the heat-consuming process: (i) exclusively electric energy, (ii) a mixture of electric energy and at least one further nonelectric energy source or (iii) exclusively nonelectric energy, where the changeover time in which the change from one energy mode to another energy mode is completed is not more than 30 minutes.

摘要:
Process for the production of synthesis gas and hydrocarbons in which a saturated hydrocarbon and an oxygen containing gas having a ratio of hydrocarbon to oxygen of greater than the stoichiometric ratio for complete combustion are introduced together with hydrogen into a bed of particulate material. The upward flow rate of the gases is sufficiently large to fluidize or to cause a spouting action of the bed material. The hydrocarbon, oxygen containing gas and hydrogen are ignited and reacted together and the products of the reaction are withdrawn.

摘要:
Biomass is processed through a biomass fractioning system that creates, through the application of selective temperature ramps and pressure shocks, a series of useful volatile components and BMF char, wherein the BMF char is reacted sacrificially with any one stream of methane, carbon dioxide, steam or oxygen to create highly pure synthesis gas with a controllable range of compositions. The resulting synthesis gas may be used in any desired manner, including conversion to oxygenates such as methanol and dimethyl ether, and to hydrocarbons.
摘要:
Process for the production of synthesis gas and higher hydrocarbons in which a saturated hydrocarbon and an oxygen containing gas having a ratio of hydrocarbon to oxygen of greater than the stoichiometric ratio for complete combustion are introduced into a bed of an inert particulate material. The upward flow rate of the hydrocarbon/oxygen containing gas stream is sufficient to fluidize or to produce a spouting action of the bed material, whereby the particulate material is thrown up above the bed surface and subsequently falls back into the bed. The hydrocarbon and oxygen containing gas are ignited reacted together, and the products of the reaction withdrawn.
