Abstract
Palladium/silica catalysts of varying dispersities were submitted to t he coking reaction with cyclopentane at 500 degrees C. Temperature pro grammed oxidation curves reveal the presence of two peaks for carbon d eposition on the metallic function: the first one near 250 degrees C w ould correspond to coke deposited on palladium atoms of high coordinat ion and the second one near 400 degrees C would involve palladium atom s of low coordination.
