The kinetics of the hydrodechlorination (HDC) of chlorobenzene has been measured over Ni supported on a range of substrates (MgO, SiO 2 , Al 2 O 3 , Ta 2 O 5 , MgO, activated carbon (AC) and graphite) of varying BET area (9-843 m 2 g -1 ) where the Ni loading was in the range 1.5-20.3% (w/w) with ca
The catalytic hydrodechlorination of chlorobenzene with NirC, PdrC and Ni Pd rC in ethanol was studied with 2 D 98 2 13 Ä 1 4 Ž . and C H NMR. Two dechlorination routes of this reaction ionic and free-radical are suggested depending upon the nature of the active hydrogen species. At the same time t
The influence of HCl production and NaOH addition on catalytic activity in the liquid-phase hydrodechlorination of chlorobenzene over palladium-supported catalysts was studied. The rate of dehydrochlorination reaction falls with time owing to the poisoning effect of HCl gradually formed as by-produc
Micro-coiled carbon fibres were prepared from the vapour phase via the catalytic pyrolysis of acetylene in the presence of Ni metal powder and a small amount of PH 3. The effects of Ni and PH 3 and of the reaction conditions and morphology on the growth of the coiled carbon fibres were examined. The
