Abstract
Oxygen in the form of an impurity in the hydrogen used deactivates a chromium oxide — activated charcoal catalyst in the hydrogenolysis of methylcyclopentane and the hydrodealkylation of ethylbenzene. In this case the selectivity of the catalyst is changed: the fraction of molecules in which the C-C bonds distant from the methyl group are cleaved, forming methyipentanes from methylcyclopentane and benzene from ethylbenzene, is increased.
