Abstract: In a method for generating various synthesis gases by electrolysis, comprising feeding steam and compressed air to the cathode and anode, respectively, of the electrolysis unit or of the first of a series of electrolysis units into the first of a series of electrolysis units, the electrolysis units are operated under an elevated gas pressure, and the oxygen-rich gas leaving the anode is subsequently expanded down to approximately ambient pressure using a gas expander. The electrolysis units are preferably solid oxide electrolysis cell (SOEC) stacks.

Abstract: In an adiabatic axial flow converter, in which process gas passes from an outer annulus via a catalyst bed, wherein the process gas is converted to a product, to an inner centre tube, the catalyst bed comprises at least one module comprising one or more catalyst layers. Feed means are arranged to provide a flow of process gas from the outer annulus to an inlet part of one or more modules, and collector means are arranged to provide a flow of product stream of converted process gas which passes axially through the catalyst bed of one or more of the modules to the centre tube.

Abstract: In a process for the oxidation of a lower alkene, such as ethylene, over a catalyst containing Cu and one or more zeolite or zeotype materials, the oxidation is conducted in the presence of ammonia in the feed gas at a process temperature below 350° C. The oxidation can be performed in a continuous process.

Abstract: Oxygen is removed from a gas feed such as a landfill gas, a digester gas or an industrial CO2 off-gas by heating the feed gas, optionally removing siloxanes and silanols from the heated feed gas, optionally removing part of the sulfur-containing compounds in the heated feed gas, injecting one or more reactants for oxygen conversion into the heated feed gas, carrying out a selective catalytic conversion of any or all of the volatile organic compounds (VOCs) present in the gas, including sulfur-containing compounds, chlorine-containing compounds and any of the reactants injected, in at least one suitable reactor, and cleaning the resulting oxygen-depleted gas. The reactants to be injected comprise one or more of H2, CO, ammonia, urea, methanol, ethanol and dimethyl ether (DME).
