A study of a HDS-catalyst deactivation using heavy petroleum fractions

Abstract

Intrinsic and engineering kinetics of the hydrodesulfurization and deasphalting of atmospheric residue of Thasos crude oil, over three successive sulfur concentrations ranges were studied by using a laboratory, stirred, high pressure, spinning catalyst basket reactor. The relevant kinetic models as well as those for the catalyst deactivation and regeneration were developed using a commercial catalyst (namely ici-41-6). The experimental measurements and the theoretical analysis resulted in the formulation of empirical kinetic equations referring to each particular of the above mentioned processes and each one of the sulfur concentration ranges. Reaction rate order and Arrhenius correlations are included in the kinetic equations.
