摘要： A method is disclosed for recovering germanium from a gaseous mixture which includes a germanium-containing compound in vapor or particulate form, acid in vapor form, and water vapor. The gaseous mixture is contacted with a liquid containing water under conditions effective to dissolve the germanium-containing compound in the liquid. The acidity of the resulting liquid mixture is increased under conditions effective to vaporize the germanium-containing compound. The vaporized germanium-containing compound is contacted with one or more aqueous solutions under conditions effective to dissolve and precipitate the germanium-containing compound in at least one of the one or more aqueous solutions, and the resulting precipitate is separated from the at least one of the one or more aqueous solutions. The methods described herein are particularly well suited for recovering germanium from the waste gases produced during optical waveguide manufacturing processes. Germanium recovered by this method can thereafter be used in the production of semiconductors, optical waveguide fibers and optical components.

摘要： The present invention relates to a chemical change reagent which is used as an additive to coal to enhance the complete combustion of the coal after turning it into a synthetic fuel. The composition is a chemical change agent in that it converts the coal/composition mix into a different material which, when burned, results in lower NOx emissions. The composition includes a wax, a base for ph adjustment and water and is mixed with the coal prior to combustion.

摘要： The invention relates to a method of treating a substantially gaseous halo-containing compound of an effluent of a glass manufacturing facility and a system for such method. The method includes the step of oxidizing the halo-containing compound to form a hydrogen and halo-containing compound. The method also includes the step of adsorbing a halogen of the hydrogen and halo-containing compound on a surface. The system includes at least one glass manufacturing apparatus which the operation of the apparatus in glass manufacturing generates an effluent which comprises a substantially gaseous halo-containing compound. The system also includes an oxidizer in fluid communication to receive the halo-containing compound and oxidize the compound to transform the halo-containing compound into a hydrogen and halo-containing compound. The system further includes a scrubber for receiving said hydrogen and halo-containing compound and absorbing the halogen from the hydrogen and halo-containing compound.

摘要： A method is provided for reducing noxious emissions from the combustion of coal or other solid fuels wherein a suspension and/or a dispersing agent is combined with a catalyst having a high surface area to mass ratio so as to optimize the reduction of emissions such as NOx. In addition, the agent and/or catalyst is applied on the surface of the fuel in an evenly distributed manner so as to maximize the contact between the agent and/or catalyst and combustion gases and further maximize reduction of emissions.
