Abstract
Neopentane conversion in hydrogen was used as a catalytic probe for ze olite encaged PdCo particles. Activity and selectivity strongly depend on the pretreatment conditions. PdCo/NaY catalysts exhibit higher iso merization selectivity than Pd/NaY in conformity with previous results on SiO2 supported Pd and PdCo. This is remarkable, because reduced Co /SiO2 displays 100% selectivity for hydrogenolysis. The isomerization selectivity thus appears to be a useful measure for the extent of allo ying between Pd and Co.
