| 英文摘要 | liquid phase hydrodechlorination of chlorinated benzenes was studied over ni/active carbon (ni/ac), ni/gamma-al2o3, ni/sio2 and raney ni. the complete dechlorination of chlorobenzene (clbz) was realized at 333-343 k on ni/ac under hydrogen atmosphere of 1.0 mpa in the presence of alkaline hydroxide. dichloro- and trichlorobenzenes were also hydrodechlorinated with 50-95% yields of benzene under the similar conditions, as above. the reaction follows zero-order to clbz concentration and 1.9 order to hydrogen pressure. the reaction does not proceed in the absence of alkaline hydroxide, suggesting the complete coverage of active nickel surface with produced chlorine and the removal of the chlorine ion with hydroxide ion as a rate-limiting step. the active catalysts were characterized by h-2 chemisorption and transmission electron microscopy techniques. the apparent activity strongly depends on the active area of nickel on catalyst surface.
