Abstract

The deactivation of two platinum black samples caused by pulses of 3-methylpentane introduced into atmospheres with different hydrogen pressures was determined by relating yields obtained in subsequent pulses to those observed over freshly regenerated catalyst. The remaining catalytic activity could be related to the amount of hydrocarbon retained on the surface as determined by radiotracer studies. The selective deactivation for isomerization and C5-cyclization as well as hydrogenolysis was interpreted in terms of multiple sites for these processes deactivated by their partial covering with carbonaceous residues formed in the first moment of reaction with hydrocarbons.
