摘要： A method for preparing a carbonaceous product includes providing oxygen, in particular from electrolysis, and providing a fuel. The method also includes combusting the fuel with the oxygen by an oxy-fuel combustion process in order to provide energy, purifying a flue gas produced by the oxy-fuel combustion process, and separating carbon dioxide from the flue gas produced by the oxy-fuel combustion process, wherein energy provided by the oxy-fuel combustion process includes, in particular exclusively, heat which is used as process heat for purifying and/or for synthesising or providing the carbonaceous product. A corresponding system is designed to carry out the described method.

摘要： 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.
