heal.abstract Catalyst deactivation data, obtained from the HDS of a Greek oil residue on a spinning basket laboratory scale reactor, are reported in this paper. Two commercial grade hydrodesulfurization (HDS) catalysts, viz. , Harshaw HT-400 E and ICI-41-6, were used in the investigation. Initial activities and modes of activity loss vs. run time are compared (HT-400 E possessed an initial activity 25% higher than that of ICI-41-6; activity was reduced to 55-65% for the former and 70% for the latter catalyst after 100 h of operation). Coke and metal deposits built up vs. run time are also reported. It is shown that C/H ratios and N//2 content of coke deposits increased proportionally with operating time. Pore volume and surface areas (% of initial value after 30 h of operation) respectively reduced for HT-400 E to 43-57 and 40-45 and for ICI-41-6 to 60-70 and 40-45. Pore structure recovery parameters following reactivation ranged between 80% and 95% of their respective initial values. en
