Abstract
This Letter reports preliminary findings on the role of chloride poiso ning during steam reforming of chlorocarbons over nickel catalysts. Wh en conversions of chlorocarbon are very high and thermal pyrolysis abs ent, the principal effect of chloride is to decrease water-gas shift a nd CH4-steam reforming activity. Product carbon dioxide/carbon monoxid e ratios are then far from equilibrium and methane remains unconverted when introduced into the feed. These results are linked to previously published surface science studies.
