  • Publication number: 20240018436
    Abstract: The present invention provides a process for obtaining solid recovered fuel and synthesis gas from a waste-based feedstock, comprising the steps of: I. converting the feedstock into a solid recovered fuel by means of a number of parameters pertaining to waste sorting, selection, comminution and/or screening; II. gasifying under suitable reaction conditions at least a portion of the solid recovered fuel to produce synthesis gas and by-product(s); and III. optionally cleaning at least a portion of the synthesis gas to produce clean synthesis gas and wastewater, wherein one or more of the solid recovered fuel, synthesis gas, and by-product(s) of the gasification are analysed during operation of the process, and wherein data from said analysis is used to control one or more parameters of step I) in order to influence reaction conditions in step II, and optionally step III).

  • Patent number: 11840668
    Abstract: An integrated process for the production of a useful liquid hydrocarbon product comprises: feeding a gasification zone with an oxygen-containing feed and a first carbonaceous feedstock comprising waste materials and/or biomass, gasifying the first carbonaceous feedstock in the gasification zone to produce first synthesis gas, partially oxidising the first synthesis gas in a partial oxidation zone to generate partially oxidised synthesis gas, combining at least a portion of the first synthesis gas and/or the partially oxidised synthesis gas and at least a portion of electrolysis hydrogen obtained from an electrolyser in an amount to achieve the desired hydrogen to carbon monoxide molar ratio of from about 1.5:1 to about 2.5:1, and to generate a blended synthesis gas, wherein the electrolyser operates using green electricity; and subjecting at least a portion of the blended synthesis gas to a conversion process effective to produce the liquid hydrocarbon product.
