    Abstract: A method for recovering resource from waste comprises: a first step for decomposing waste into ash and reformed gas by performing a partial- combustion, a thermal decomposition, and a reforming process with using only oxygen; a second step for pre-processing the ash obtained in the first step; a third step for recycling the ash pre-processed in the second step into resource by a melting process; a fourth step for recovering sensible heat of the reformed gas obtained in the first step, and separating sooty carbon from the reformed gas by a dust-collecting process thereby recycling the sooty carbon into active carbon in an another process; a fifth step for purifying the reformed gas having undergone a dust- collecting process in the fourth step into clean fuel gas by neutralization, desulfurization, and absorption processes, and recycling waste water produced as a byproduct; and a sixth step for utilizing the clean fuel gas obtained in the fifth step. Accordingly, the amount of pollutants contained in final disposal to atmosphere are minimized, and all of the waste is recycled into useful resource. Also, the operation cost (running cost) is reduced significantly.

    Abstract: The invention relates to a process and apparatus for the production of thermal and electric energy in a pulp mill, in particular a sulfate pulp mill, according to which process and waste liquor of the cellulose pulp cooking liquor is concentrated, and this concentrated liquor is burned in the recovery boiler in the presence of biogenic fuels, in which case the thermal energy is recovered from the flue gases from the combustion, and this thermal en­ergy is, when so desired, converted to electric energy. According to the invention, the biogenic fuel used is wood bark or similar waste wood, which is dried to a moisture content below 30 %, whereafter it is gasified to fuel gas, which is fed into the recovery boiler. The process according to the invention makes the acquisition of a separate bark boiler in pulp mills completely unnecessary, which significantly lowers the investment costs. The process simplifies the apparatus, its operation and maintenance, and improves energy efficiency.

    Abstract: A staged gasification process and system for thermal gasification of special waste fractions and biomass, e.g. wood comprises a drier (1), in which the fuel is dried by contact with superheated steam. The dried fuel is fed into a pyrolysis unit (4) to which superheated steam is also supplied. The volatile tar containing components produced in the pyrolysis unit (4) is passed to an oxidation zone (5) in which an oxidation agent is added so as to cause a partial oxidation, whereby the content of tar is substantially reduced. The solid fuel components from the pyrolysis unit (4) may be fed into a gasification unit (6) to which hot gases from the oxidation zone (5) are supplied. In the gasification unit (6) the solid fuel components are gasified or converted to carbon. The gas produced in the gasification unit (6) may be burnt in a combustion unit (7), such as a combustion engine. Thus, a gasification process is obtained for gasification of biomass and waste with a high energy efficiency, low tar content of the gasification gas, with moderate risk of slagging for a wide spectrum of fuels, including fuels with a large content of moisture.

    Abstract: A system and method generates electricity and co-produces a hydrogen flow from coal. The electricity is generated by a turbine with a topping combustor and a solid oxide fuel cell ("SOFC") reacting syngas. The syngas is produced in a coal gasifier with a portion of the compressed air from the turbine, coal, and steam. Prior to the syngas being delivered to the topping combustor and the SOFC, it is cleaned and a portion of the hydrogen in the syngas is removed to form the hydrogen flow. Additionally, a vitiated air flow from the SOFC is directed to the topping combustor and another portion of the compressed air from the turbine directed to the SOFC after it is heated with the turbine exhaust. An aspect of the invention varies the amount of electricity generated and the volume of hydrogen co-produced based upon the demand of electricity and/or the demand of said hydrogen.
