Process and plant for producing methanol, the process comprising the steps of: a) providing a raw synthesis gas stream; b) water gas shifting at least a portion of the raw synthesis gas stream, thereby producing a shifted synthesis gas; c) preparing a separate hydrogen containing stream and a separate oxygen containing stream by electrolysis of a water feedstock; d) introducing at least a portion of the separate hydrogen containing stream into shifted synthesis gas, thereby producing a methanol synthesis gas; and e) converting the methanol synthesis gas into said methanol.

Systems and methods for producing green hydrogen from a source material (e.g., biowaste) are contemplated. The source material is at least partially dehydrated to produce a dried intermediate and recovered water. The dried intermediate is pyrolyzed to produce syngas and a char. The recovered water is electrolyzed to produce oxygen and green hydrogen.

The invention relates to a method for recycling carbon-containing composite materials having a carbon-containing matrix material and fibre-, filament- or wire-reinforcement, in particular glass-fibre- or carbon-fibre-reinforced plastics materials, GFRP/CFRP, wherein the method comprises the following steps: at least extensive separation of the reinforcement from the carbon-containing matrix material; gasifying and/or pyrolysing the carbon-containing matrix material in order to produce synthesis gases containing hydrogen and carbon monoxide or a fluid mixture containing hydrocarbons; and processing the products of the gasifying and/or the pyrolysing to form at least one, preferably liquid, fuel; wherein separating the reinforcement from the carbon-containing matrix material comprises coarse comminution of the composite material by cutting and/or crushing, fine comminution of the coarsely comminuted composite material by pressing and/or squeezing in order to release the comminuted reinforcement from the comminuted composite material, and separating the released comminuted reinforcement from the comminuted matrix material.

A fuel production system and a fuel production method are provided which can efficiently perform adjusting of a synthesis gas composition by hydrogen supply, while suppressing the generated amount of carbon dioxide by a system overall. A fuel production system includes: a gasification furnace which gasifies a biomass raw material to generate a synthesis gas containing hydrogen and carbon monoxide; a liquid fuel production device which produces a liquid fuel from the synthesis gas generated by the gasification furnace; a hydrogen supply pump which supplies hydrogen to a raw material supply area or a synthesis gas discharge area; a byproduct sensor which detects a byproduct amount generated inside the gasification furnace; and a controller which switches a hydrogen supply location by the hydrogen supply pump between the raw material supply area and synthesis gas discharge area, based on the byproduct amount detected by the byproduct sensor.

A process for synthesising hydrocarbons is described comprising the steps of (a) making a synthesis gas comprising hydrogen, carbon monoxide and carbon dioxide from a feedstock in a synthesis gas generation unit, (b) removing carbon dioxide to produce a carbon dioxide stream and purified synthesis gas comprising hydrogen and carbon monoxide for synthesis in a Fischer-Tropsch hydrocarbon synthesis unit wherein (i) at least a portion of the FT water stream is fed to an electrolysis unit to provide an oxygen stream, which is fed to the synthesis gas generation unit. Carbon dioxide stream recovered from the carbon dioxide removal unit and a portion of the hydrogen stream produced by the electrolysis unit are fed to a reverse water-gas shift unit to produce a carbon monoxide stream, with carbon monoxide stream from the reverse water-gas shift unit is fed to the Fischer-Tropsch hydrocarbon synthesis unit.
