Catalyst activity is decreased more if the catalyst is prereduced rather than precarburized before contact with poison. The inhibiting effect of water on the reaction rate decreases more markedly with increasing temperature on a poisoned catalyst than on an unpoisoned catalyst. Formation of methane is significantly less on poisoned catalysts than unpoisoned catalysts. On both poisoned and unpoisoned catalysts, the olefin/paraffin ratio decreases with increased CO conversion and isomerization of ..cap alpha..- to ..beta..-olefins increases. Isomerization activity is greater on a prereduced/poisoned catalyst than on a precarburized/poisoned catalyst. 11 references, 23 figures, 3 tables.
