摘要： 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).-

摘要： The present invention provides a process for the manufacture of a synthetic fuel comprising gasifying a carbonaceous feedstock comprising waste materials and/or biomass to generate a raw synthesis gas; supplying the raw synthesis gas to a primary clean-up zone to wash particulates and ammonia or HCl out of the raw synthesis gas; contacting the synthesis gas in a secondary clean-up zone with a physical solvent for sulphurous materials; contacting the desulphurised raw synthesis gas in a tertiary clean-up zone with a physical solvent for CO2 effective to absorb CO2; removing at least part of the absorbed CO2 in a solvent regeneration stage to recover CO2 in a form sufficiently pure for sequestration or other use; and supplying the clean synthesis gas to a further reaction train to generate a synthetic fuel.

摘要： A catalyst is regenerated by an inventive process using a heat exchange fluid such as superheated steam to remove heat during the process relying on efficient heat transfer (e.g., enabled by the microchannel reactor construction) in comparison with prior art heat exchange relying on a phase change, e.g. between water and (partial or complete vaporization) steam, allows simplification of the protocols to enable transition at higher temperatures between steps which translates in reduced duration of the regeneration process and avoids potential water hammering risks.

摘要： In a process for treating wastewater from a combined gasification and Fischer-Tropsch (F-T) process, feedstock derived from Municipal Solid Waste or the like is gasified in a reactor (R) and treated in a cleanup unit (C) which generates a first wastewater stream (1st WWT STREAM) containing salts and inorganic pollutants. The first wastewater stream is treated in a treatment unit (T1) to remove inorganic pollutants derived from the syngas. The treatment comprises a) degassing, and subsequently b) neutralising the first wastewater stream before treatment in a Dissolved Air Flotation unit (72c) and filtering in a moving sand bed or similar (72d) to remove solids, and a stripping process to remove ammonia. A second wastewater stream (2nd WWT Stream) containing organic pollutants but being low in salts arises from the F-T process and is treated separately to allow recycling within the F-T process.

摘要： The present invention provides a process for the manufacture of a useful product from carbonaceous feedstock of fluctuating compositional characteristics, the process comprising the steps of: continuously providing the carbonaceous feedstock of fluctuating compositional characteristics to a gasification zone; gasifying the carbonaceous feedstock in the gasification zone to obtain raw synthesis gas; recovering at least part of the raw synthesis gas from the gasification zone and supplying at least part of the recovered raw synthesis gas to a partial oxidation zone; equilibrating the H2:CO ratio of the raw synthesis gas in the partial oxidation zone to obtain equilibrated synthesis gas; recovering at least part of the equilibrated synthesis gas from the partial oxidation zone and treating the gas to remove impurities and generate a fine synthesis gas; optionally adjusting the H2:CO ratio of at least part of the fine synthesis gas to obtain adjusted fine synthesis gas; and converting the optionally adjusted fine synthesis gas into the useful product in a further chemical reaction requiring a usage ratio; wherein the fine synthesis gas H2:CO ratio is below the usage ratio and wherein any optional adjustment of at least part of the fine synthesis gas H2:CO ratio is effective to increase the H2:CO ratio in the fine synthesis gas to a level at, nearer to or above the usage ratio; wherein the H2:CO ratio of the raw synthesis gas fluctuates during operation of the process as a result of the fluctuating compositional characteristics of the carbonaceous feedstock by a percentage of ±x; and the H2:CO ratio of the equilibrated synthesis gas does not fluctuate during operation of the process or fluctuates during operation of the process as a result of the fluctuating compositional characteristics of the carbonaceous feedstock by a percentage±y, y being a lower percentage than x.
