摘要：

The catalytic hydrogenation of nitrite in water to nitrogen over Pd-supported on different woven fibrous materials is studied. Low porosity carbon fibers, low porosity D-type glass fibers and composite (glass covered by gamma -aluminia) fibers are used. The dispersion of Pd is compared for different supports at various Pd-loadings and correlated with the catalytic activity. The ammonia as an undesired by-product was also observed and the main parameters suppressing its formation are discussed. A reactor concept based on woven fibrous catalysts is suggested and the main design parameters for the technical application are estimated. (C) 2001 Elsevier Science B.V. All rights reserved.
