heal.abstract	The kinetics of the catalytic hydrodesulphurization of a deasphalted oil, obtained from the atmospheric residue of the Greek Thasos crude oil, as well as of the asphaltenic and non-asphaltenic fraction of the residue were investigated. A batch recycle trickle bed reactor was used for the desulphurization experiments, which were carried out at a pressure of 50 bar and temperatures in the range of 350 - 400°C. A second order kinetic equation describes very well the desulphurization rates of both the deasphalted oil and the non-asphaltenic fraction of the residue. The activation energy was found to be 19 kcal (mol-1 S) in both cases and the values of the rate constants were identical. The desulphurization rates of the asphaltenic fraction of the residue are well described by a third order kinetic equation. The activation energy was calculated as 53 kcal (mol-1 S). The effect of the presence of asphaltenes on the hydrodesulphurization rates of the non-asphaltenic molecules is discussed and a qualitative model for the hydrodesulphurization reactions of asphaltenes is presented. © 1986.	en
