2009/9/9
Uplandization” is the process that changes the physical and chemical properties in a paddy field into those of an upland field. There is a transitional period when a paddy field is converted to an upl...
Catalytic Activity of Iron Oxides Supported on γ-Al2O3 for Methane Oxidation
Iron oxide catalyst Goethite Hematite catalyst Alumina support
<
2009/7/24
Three kinds of catalysts of goethites supported on γ-Al2O3 (Fe/γ-Al2O3), SiO2-Al2O3 (Fe/SiO2-Al2O3) and SiO2 (Fe/SiO2) were investigated in terms of the catalytic activity of methane oxidation. The sp...
