Effectiveness factors for reactions between volatile and non-volatile components in partially wetted catalystsEffectiveness factors for reactions between volatile and non-volatile components in partially wetted catalysts Peer-Reviewed Journal Publication Δημοσίευση σε Περιοδικό με Κριτές 2015-10-291987enA steady state model is formulated to describe the reactions between one gaseous and two non-volatile components on partially wetted catalysts in a trickle-bed reactor. Unlike previous studies, the model does not assume a gaseous or liquid limiting reactant. The computed results show the effect of intraparticle and interphase mass transfer resistances as well as of wetting efficiency and number and location of wetted zones on catalyst performance. Maximum effectiveness factors are generally obtained with intermediate values of the wetting efficiency. The model is applied to a typical HDS process of heavy gas oil in trickle-bed reactors.http://creativecommons.org/licenses/by/4.0/Chemical Engineering Science4261323-1332 Gentekakis Ioannis Γεντεκακης Ιωαννης Vayenas, Costas G Elsevier Partially wetted catalysts
