  • Activities of different metal oxide catalysts on NO reduction and CO oxidation

    A series of transition metal oxide catalysts (Zn, Ti, Cu, Ni, Fe and V) supported on Al2O3 and SiO2 were prepared using the incipient wetness impregnation method. Their performances on NO reduction and CO oxidation followed the sequence of TiO2 > CuO/ZnO > CuO > ZnO. TiO2 supported on SiO2 was more active than that on Al2O3, while ZnO had the opposite performances. The activities of CuO/Al2O3 and ...

  • Selective catalytic reduction of nitric oxide over copper oxide and cerium oxide catalysts

    The selective catalytic reduction of nitric oxide with hydrocarbons in an oxygen-containing simulated flue gas has been investigated for a series of copper oxide and cerium oxide alumina supported catalysts at 600–775 K. The activity of these catalysts for the reduction of NO by methane or propane has been investigated in simulated flue gas. The effects of sulphates on the catalyst, and of water ...

  • TOC Analysis for Standard Methods 5310B: High-Temperature Combustion Method

    Introduction Total Organic Carbon (TOC) is a rapid method that analyzes for organic carbon and expresses the result as the amount of carbon found. It is a non-specific method unable to distinguish between various organic species and only indicates that organic carbon compounds are present. Organic carbon analyzers operate by the determination of the amount of total carbon present in a ...

  • Preparation and characterization of nickel based catalysts for partial oxidation of methane

    Hydrogen, which can be used in many fields without polluting the environment, is thought to be the cleanest fuel source of 21th century. Therefore, low cost production, facile storage and transportation of hydrogen are important research subjects that are investigated by many universities and related commercial facilities. Steam-hydrocarbon reforming is the major hydrogen production process ...

  • Activated carbon cloth: a potential adsorbing/oxidizing catalyst for phenolic wastewater

    An investigation into the use of activated carbon cloth (ACC) as a potential adsorbent and/or catalyst for oxidation processes is reported. The extent of increase/decrease of oxidation/adsorption of phenol, as measured by total organic carbon content (%), is explained by considering the effects of the oxidants such as ozone and hydrogen peroxide on the activated carbon cloth. Results also show ...

  • Recovery of Precious Metal Catalysts - A New Process Using Supercritical Water Oxidation

    Up to now, the recovery of precious metals used as catalysts in chemical processes has involved the use of incineration. Now, however, a British-Swedish joint venture has developed a process which uses supercritical water oxidation instead, which provides many economic and environmental advantages. Precious metals are used extensively in catalysts in a wide range of industrial chemical processes. ...

  • Oxidation of cosmetic wastewaters with H2O2 using a Fe/γ-Al2O3 catalyst

    A catalyst based on Fe supported on γ-Al2O3 has been prepared and tested for catalytic wet peroxide oxidation (CWPO) of cosmetic wastewaters. The influence of the main operating conditions (space-time, temperature, and H2O2 dose) have been investigated. Working with this self-made Fe/γ-Al2O3 catalyst at 85°C, with a space-time of 9.4 kgcat h/kgCOD and a dose of H2O2, corresponding to 0.5 times ...

  • Dirt, The Ultimate Catalyst

    AbstractA catalyst is a substance which alters the rate of a chemical reaction but is not consumed in the reaction.  In earlier days of chemical processing, catalysts used to promote commercial chemical processes were most often made of inordinately expensive Aprecious metals such as platinum or rhodium. Over the last decade or so, Abase metal catalysts such as manganese oxide and copper ...


  • Caltech working to solve the world`s energy problems with the help of inVia

    Fossil fuels are the world's main fuel source for transportation, heating and generating electricity. As a by-product, high levels of CO2 are released into the atmosphere. With the drive for sustainable energy production, a method that generates easily-stored fuel from sunlight—and absorbs CO2—is a very attractive proposition. The California Institute of Technology ...
