heal.abstract	A spinning basket reactor was used to investigate the hydrodesulfurization (HDS) kinetics of Greek (Thasos) atmospheric residue. The effects of temperature (285-395°C), pressure (30-70 bar), and particle size (L̄p = 5.67 × 10-3-58.9 × 10-3 cm) upon the intrinsic reaction rate were determined. Two commercial HDS supported catalysts (Co-Mo/γ-Al2O3) differing in their chemical composition and physical structure were employed. It was shown that the overall HDS reaction rate was kinetically controlled when the pulverized catalyst was rotated at a rate of 2540 rpm. Parameters defined by a general lumped kinetic equation, incorporating a hydrogen inhibition term, were obtained for both catalysts. The following kinetic equations were developed: (i) catalyst HT-400 E, R1 = 2.799 × 1010 exp(-34970/RT)PH2CS1.9/(1 + 0.0036PH2); (ii) catalyst ICI-41-6, R2 = 4.962 × 1010 exp(-32590/ RT)PH2CS2.3/ (1 + 0.0050PH2). Evaluations of effectiveness factors and effective diffusion coefficients reported in this paper and associated with the use of particular catalyst pellet sizes were based on HDS standard experiments. © 1987 American Chemical Society.	en
