1. Design and Operation of a Chemical-Looping Reformer for Catalytic Upgrading of Biomass-Derived Gas
Abstract : AbstractThe removal of tar from the raw gas produced during biomass gasification is necessary before the gas can be used as a feedstock for synthetic fuels. The currently commercially available technologies for gas cleaning, i.e. READ MORE

2. SiCFET gassensors : theory, developent, and applications to flue gas cleaning processes in power plants
Abstract : Environmental and health concerns lead to stricter regulations on power plant emission. Sensors play an important role, not only as part of the process control to ensure that the effluent stays under the regulated values, but also to increase the pollution removal efficiency and to decrease the reagent consumption.

3. Externally fired gas turbine cycle based on biomass gasification gas as fuel
Abstract : Energy services are essential for the development of societies, reduce poverty, and improve the living standards of inhabitants. The conventional routes to provide energy services employ fossil fuels. However, this involves environmental and availability concerns. READ MORE

4. Mercury and dioxins in a MercOx-scrubber
Abstract : The removal of mercury and the absorption of dioxins in an acid wet scrubber have been studied in industrial scale. Hydrogen peroxide is added as an oxidizing agent to the scrubber liquid with the purpose to remove SO2 and enhance the removal of mercury. READ MORE

5. The relationship between fly ash chemistry and the thermal formation of polychlorinated pollutants during waste incineration
Abstract : The thermal formation of polychlorinated dibenzo-p-dioxins (PCDDs), dibenzofurans (PCDFs), biphenyls (PCBs), and naphthalenes (PCNs) is a major problem in waste incineration. Ideally, rather than relying on air cleaning systems and treatment techniques, their formation should be minimized or, if possible eliminated. READ MORE
