Structured composite catalyst Pd/Ce_(0.75)Zr_(0.25)O_(2-x)/θ-Al_2O_3/FeCrAlloy for complete oxidation of methane

摘要

Structured catalyst Pd/Ce0.75Zr0.25O2-x/Al2O3/FeCrAl was prepared via multistep solution synthesis. The prepared catalyst was characterized by X-Ray diffraction analysis (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), the specific surface area was measured by N-2 adsorption (BET). The catalyst was tested in the deep oxidation of methane at excess air ratio ranging from 1.05 to 2. During the tests, the catalyst ensured complete methane conversion and zero CO content in the exhaust gases.
