Reduction of nitrite-ions in water over Pd-supported on structured fibrous materials

Catalytic hydrogenation of NO2- in water to N2 over Pd-supported on different woven fibrous materials was studied. Low porosity C fiber, low porosity D-type glass fiber, and composite (glass covered by g-Al2O3) fiber were used. Pd dispersion was compared for different supports at various Pd loadings and correlated with catalytic activity. NH3 as an undesired byproduct was also obsd. and main parameters to suppress its formation are discussed. A reactor concept based on woven fibrous catalysts is suggested and main design parameters for tech. application were estd. [on SciFinder (R)]
