    摘要： Methods are disclosed for achieving the catalytic combustion of a gaseous species in low temperature humid environments. The methods comprise the steps of obtaining a combustion catalyst composition comprising an amount of a precious metal supported on an ion-exchangeable alkali metal titanate substrate, and then exposing the species to the combustion catalyst composition in the presence of an oxygen containing gas and water vapour at a catalysis temperature below 200° C. and at a relative humidity above 0.5%. A novel desiccant-coupled catalytic combustion process and system are also disclosed.

    摘要： An inventive adsorptive gas separation process is provided capable of producing a purified methane product gas as a light non-adsorbed product gas as opposed to a heavy desorbed exhaust gas component, from a feed gas mixture comprising at least methane, and carbon dioxide. In an embodiment of the invention, the feed gas mixture may comprise at least about 10% carbon dioxide, and the purified methane product gas may be desirably purified to contain less than about 5000 ppm carbon dioxide. In another embodiment of the invention, the feed gas mixture may comprise at least about 50% carbon dioxide, and the purified methane product gas may be desirably purified to contain less than about 5000 ppm carbon dioxide.

    摘要： Sensors and methods for detecting combustible gases in a gas mixture are disclosed based on combustion catalyst compositions comprising an amount of a precious metal supported on an ion-exchangeable alkali metal titanate substrate. The sensors and methods are particularly useful for measuring the concentration of combustible gases in low temperature and high humidity conditions. Advantageously, certain embodiments can selectively measure the concentration of select species (e.g. ethylene).

    摘要： High density adsorbent structures may be constructed in parallel passage contactor configurations using improved high density adsorbent sheets. Improved high density adsorbent sheets may be formed using adsorptively active support or substrate materials upon which adsorbent material is applied, such as by coating processes, so that in the resulting high density adsorbent structure both the substrate and the coated adsorbent material are active in adsorption processes. Alternatively, improved high density adsorbent sheets may be formed comprising precursor materials, such as certain clays, which may be coated onto known support materials and thereafter converted to active adsorbent materials using known conversion techniques. This produces high-density adsorbent sheets comprising adsorbent material without inert binder material fractions. Improved self-supporting adsorbent sheets also may be formed without using support material, resulting in higher adsorbent densities relative to known adsorbent sheets.
