  • Thin Wall Ceramics as Monolithic Catalyst Supports

    2021-3-12 · In the present study the catalytic activities of several TiO2-supported metal and metal oxide catalysts have been tested simultaneously for the selective catalytic reduction of nitrogen oxides with ammonia (NH3-SCR) using high-throughput-screening equipment. Two different series of various catalyst samples were evaluated for different feed gas compositions, both with and without water, and ...

  • Screening of TiO2-Supported Catalysts for Selective

    2020-2-29 · ABSTRACT With its industrial applicability and low energy consumption, a process for implementing the NH3-SCR of NO at low temperatures is urgently needed. In this study, MnOx-CeO2/TiO2 (MnCe/Ti) catalysts doped with different amounts of Ce were prepared and experimentally examined for their NH3-SCR activity between 100°C and 400°C. Adding a small amount of Ce (at the …

  • Effect of Ceria Doping on the Catalytic Activity and

    Catalytic activity of hexaaluminates Sr _<0.8>La_<0.2>Al_<12>O_<19> (SLA) and Sr_<0.8>La_<0.2>MnAl_<11>O_<19> (SLMA) impregnated with Pd (NO_3)_2 was investigated for combustion of CH_4.Although Pd-SLA showed a decrease in its activity at 700-800゚C due to reduction of PdO,high oxidation activity of SLMA compensated this influence, resulting in stable combustion by …
