Abstract. Catalytic reduction of nitrate (NO3-) in groundwater over a Cu–Pd catalyst supported on active carbon was investigated in a gas–liquid co-current flow system at 298 K. Although Cu–Pd/active carbon, in which the Cu/Pdmolar ratio was more than 0.66, showed high activity, high selectivity for the formation of N2 and N2O (98%), and high durability for the reduction of 100 ppm N…

Abstract. The sulfated zirconia project was carried out in order to obtain a broad understanding of the preparation, characterization, and application of the solid superacids of sulfated zirconia. The sulfated zirconia catalysts were prepared by the equilibrium adsorption method and the ammonium sulfate kneading method using the reference catalysts JRC-ZRO-2, -3, -4, and -5, supplied by the…

Abstract Preferential oligomerization of isobutene in a mixture of isobutene and 1-butene (molar ratio of 1:1) over H4SiW12O40/SiO2 was investigated with different loadings of H4SiW12O40. The catalytic performance of H4SiW12O40/SiO2 was compared with those of typical solid acids, such as H-b, SiO2-Al2O3, and SO4 2/ ZrO2. H4SiW12O40/SiO2 was superior in activity and selectivity for isobute…
