Abstract: A power-to-X system for the utilization of off-gases, includes an electrolyzer for generating hydrogen H2 and oxygen O2, a unit, connected to the electrolyzer, for processing the hydrogen H2, for removing any remaining water H2O and oxygen O2 from the generated stream of hydrogen H2, a compressor, connected to the unit for processing the hydrogen H2, for compressing the hydrogen H2, and a chemical reactor, connected to the compressor, for producing a synthesis gas consisting of hydrogen H2 and carbon dioxide CO2 that can be added. An oxy-fuel combustion system to which non-condensable off-gases from the chemical reactor and oxygen O2 from the electrolyzer can be supplied, and carbon dioxide CO2 generated during the combustion of the off-gases in the oxy-fuel combustion system can be returned to the stream of hydrogen H2 downstream of the electrolyzer via a return line.

Abstract: A method for gasification of fuel in an entrained flow of a gasification reactor. The method includes jointly gasifying a mixture of at least two different fuels having different degrees of coalification, including those of differing coal qualities such as brown coals and stone coals. The method also includes pulverizing the coals forming the mixture in specific grain bands and drying the coals forming the mixture to a specific residual water content.

Abstract: A reactor is proposed for entrained flow gasification for operation with pulverized or liquid fuels, with an externally cooled draft tube protecting the slag discharge outlet. An outlet of the draft tube remains above a water line of a sump of the reactor and is formed from Molybdenum, an alloy featuring molybdenum, Tantalum or an alloy featuring Tantalum.

Abstract: The invention relates to a gasification method which, with a reliable and safe mode of operation, allows the simultaneous gasification of coals of different degrees of coalification, including those of differing coal qualities such as brown coals and stone coals, with the pulverized fuel consisting of the mixture of the different coals being fed from a common dispensing system to the gasification reactor.

Abstract: A reactor is proposed for entrained flow gasification for operation with pulverized or liquid fuels, with liquid fuels being understood as oils containing solids as well as suspensions of water or oil with combustible materials crushed into fine dust or anorganic additives, at pressures between ambient pressure and 8 MPa, gasification temperatures between 1,200 and 1,900° C., as well as with a gasification means containing free oxygen, which features a reaction chamber, a gasification burner which is arranged in the upper area of the reaction chamber, a quench chamber, which is connected via a crude gas and slag discharge outlet to the reaction chamber, a draft tube protecting the slag discharge outlet. The draft tube of this reactor is inventively formed from Molybdenum, an alloy featuring molybdenum, Tantalum or an alloy featuring Tantalum. The choice of these materials enables a previously complicated installation to be greatly simplified by omitting the cooling previously required.

Abstract: A method and device for the gasification of pulverized fuels from solid fuels such as bituminous coals, lignite coals, and their cokes, petroleum cokes, coke from peat or biomass, in entrained flow, with an oxidizing medium containing free oxygen, by partial oxidation at pressures between atmospheric pressure and 80 bar, and at temperatures between 1,200 and 1,900° C., at high reactor capacities between 1,000 and 1,500 MW. The method uses the following steps: metering of the fuel, gasification reaction in a gasification reactor with cooled reaction chamber contour, quench-cooling, crude gas scrubbing, and partial condensation.
