Abstract:
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.
Abstract:
The invention relates to a process for utilizing a hydrocarbon-comprising and/or carbon dioxide-comprising coproduct gas, accompanying gas and/or biogas, wherein hydrocarbon-comprising and/or carbon dioxide-comprising coproduct gas, accompanying gas and/or biogas is introduced into a reaction space and the multicomponent mixture comprised in the coproduct gas, accompanying gas and/or biogas is converted in a high-temperature zone at temperatures of more than 1000° C. and in the presence of a carrier into a product gas mixture which comprises more than 95% by volume of CO, CO2, H2, H2O, CH4 and N2 and optionally into a carbon-comprising solid which is deposited to an extent of at least 75% by weight, based on the total mass of the carbon-comprising solid, on the carrier where the flow velocity of the gas mixture of coproduct gas, accompanying gas and/or biogas in the reaction zone is less than 20 m/s.
Abstract:
The present invention relates to a process for direct amination of hydrocarbons to amino hydrocarbons, comprising (a) the reaction of a reactant stream E comprising at least one hydrocarbon and at least one aminating reagent to give a reaction mixture R comprising at least one amino hydrocarbon and hydrogen in a reaction zone RZ, and (b) electrochemical removal of at least a portion of the hydrogen formed in the reaction from the reaction mixture R by means of at least one gas-tight membrane electrode assembly which is in contact with the reaction zone RZ on the retentate side and which has at least one selectively proton-conducting membrane, at least a portion of the hydrogen being oxidized over an anode catalyst to protons on the retentate side of the membrane, and the protons, after passing through the membrane, being partly or fully reacted with an oxidizing agent over a cathode catalyst to give water on the permeate side, and the oxidizing agent originating from a stream O which is contacted with the permeate side of the membrane.
