Abstract

The temperature programmed-desorption (TPD) of butane, butene, butadiene and thiophene over a series of $Co-Mo/\gamma-Al_20_3$ catalysts with varying Co to Mo ratio has been investigated. The TPD of butane, butene and butadiene over catalysts containing no Co showed a single desorption profile while incorporation of Co created an additional site without significantly affecting desorption from the original site. The TPD of thiophene over a series of catalysts with varying Co content showed identical desorption temperature as well as heat of desorption. It was concluded that thiophene was adsorbed on the "Mo-S" component of the catalyst and was unaffected by the presence of Co.
