摘要： A method and apparatus for mineralizing organic contaminants in water or air provides photochemical oxidation in a unique two-phase or three-phase boundary system formed in each pore of a TiO.sub.2 membrane in a photocatalytic reactor. In the three-phase system, gaseous oxidant, liquid contaminant, and solid semiconductor photocatalyst having a metal catalyst disposed thereon meet and engage in an efficient oxidation reaction. The porous membrane has pores which have a region wherein the meniscus of the liquid varies from the molecular diameter of water to that of a capillary tube resulting in a diffusion layer that is several orders of magnitude smaller than the closest known reactors. The photocatalytic reactor operates effectively at ambient temperature and low pressures.

摘要： Apparatus and method for cleaning air. An air cleaner includes a housing that defines an airflow pathway and a catalytic reactor having a catalyst secured on a porous substrate that is disposed transverse to the airflow pathway. Preferably, the catalyst includes a light activated oxidizing photocatalyst or a thermally activated oxidizing catalyst. A photocatalytic reactor will include a light source directed at a light activated oxidizing photocatalyst, such as TiO2 particles or a binary oxide particle species, which is disposed on the porous substrate. Most preferably, a metal catalyst is disposed on the photocatalyst particles at a concentration or loading between about 0.01 wt % and about 5 wt %. The air cleaner may further comprise an adsorption matrix upstream of the catalytic reactor, optionally in combination with a heater. A particulate filter and/or an electrostatic precipitator may also be disposed upstream of the adsorption matrix and the catalytic reactor.

摘要： The invention relates to a process for electrochemically converting anhydrous hydrogen halide, such as hydrogen chloride, hydrogen fluoride, hydrogen bromide and hydrogen iodide, to essentially dry halogen gas, such as chlorine, fluorine, bromine and iodine gas, respectively. In a preferred embodiment, the present invention relates to a process for electrochemically converting anhydrous hydrogen chloride to essentially dry chlorine gas. This process allows the production of high-purity chlorine gas. In this process, molecules of essentially anhydrous hydrogen chloride are transported through an inlet of an electrochemical cell. The molecules of the essentially anhydrous hydrogen chloride are oxidized at the anode of the cell to produce essentially dry chlorine gas and protons, which are transported through the membrane of the cell. The transported protons are reduced at the cathode to form either hydrogen gas, water or hydrogen peroxide.

摘要： The invention provides an improved proton exchange membrane for use in electrochemical cells having internal passages parallel to the membrane surface comprising permanent tubes preferably placed at the ends of the fluid passages. The invention also provides an apparatus and process for making the membrane, membrane and electrode assemblies fabricated using the membrane, and the application of the membrane and electrode assemblies to a variety of devices, both electrochemical and otherwise. The passages in the membrane extend from one edge of the membrane to another and allow fluid flow through the membrane and give access directly to the membrane.
