摘要： Embodiments described herein generally relate to a composite carbonate utilized as a catalyst in coal gasification processes. Methods described herein also include suitable processing conditions for performing coal gasification with the composite catalyst. In certain embodiments the composite catalyst may comprise an alkali carbonate and a transition metal carbonate, for example, an FeCO3—Na2CO3 catalyst. An FeCO3—Na2CO3 catalyst, compared to raw coal, may increase the carbon conversion rate by about two times within the 700° C.-800° C. range due to its ability to reduce the activation energy of gasification by about 30-40%. Compared to pure sodium and pure iron catalysts, the composite catalyst may increase the yields of desired products H2 and CO at 800° C. by 14.8% and 40.2%, respectively.

摘要： The invention relates to a method for producing fuel from organic waste or biomass in a gasification process comprising the burning of organic waste or biomass and the recovery of the gasification residue. The method comprises at least the following steps: organic aqueous waste or biomass (M; M1) is fed in a combustion chamber (1); oxygen-bearing pressurized regeneration gas (G) is also fed in said combustion chamber (1); a continuous, pressurized combustion process is maintained in the combustion chamber, without adding an external oxygen source or heat in the process, so that the combustion of organic waste or biomass is carried out with the oxygen content of 0.1-1 of the stoichiometric oxygen content, as the oxygen maintaining the combustion and the overpressure and heat created in the combustion chamber (1) are completely derived from the pyrolysis of the regeneration gas and/or from the pyrolysis of the aqueous organic waste or biomass (M; M1) fed in the combustion chamber, and from the gasification reactions between the supplied material (M1) and the regeneration gas (G); ash (A) created in the continuous gasification process taking place in the combustion chamber (1) is removed and combustion gases obtained from the gasification process, together with solid particles contained in the combustion gases, are conducted to a separation process; in the separation process, the temperature of the combustion gas (S) is dropped below the flash point (Fp) of the compounds contained in the combustion gas and below the water condensation point, the condensation water (W) contained in the combustion gas (S) removed, the liquid fuel (M; M4) is recovered from the combustion gas (S) and the regeneration gas (G) contained in the combustion gas is completely or partly conducted back to the combustion chamber (1).

摘要： This invention provides a system and method for pyrolyzing and/or gasifying material such as organically coated waste and organic materials including biomass, industrial waste, municipal solid waste and sludge. In a first mode of operation the method/system heats the material in a processing chamber (10) by passing hot gas therethrough. This pyrolyzes and/or gasifies the organic content it to produce syngas and, invariably, soot. In a second mode of operation the method/system increases the oxygen content of the hot gas such that the oxygen within the hot gas reacts with the heated soot to form carbon monoxide.

摘要： Gasifiers for the gasification of solid carbon-based fuels are disclosed herein. An example gasifier includes an inlet chamber for introducing fuel into the gasifier and a pyrolysis region for pyrolyzing the fuel introduced into the vessel. The pyrolysis region includes first means for admission of a pyrolysis agent. The example gasifier also includes a combustion region for incinerating pyrolysis gases originating from the pyrolysis region, where the combustion region includes second means for admission of a gasifying agent. Also, the example gasifier includes a reduction region for gasifying carbonized fuel originating from the pyrolysis region, an outlet for collecting gases originating from the reduction region, and a region for collecting and discharging ashes. In addition, the example gasifier includes active transfer means to actively transfer solid material from the pyrolysis region to the reduction region. In some examples, the active transfer means is located between the pyrolysis region and the combustion region, and the active transfer means includes a transfer chamber to prevent a direct flow of the solid material from the pyrolysis region to the reduction region, where the transfer chamber is permeable to the pyrolysis gases.
