Investigation of the Activity of Two Cobalt-Molybdenum-Alumina Catalysts for Hydrodesulfurization of FMC Oil, a Coal-Derived Liquid
Abstract
Two Cobalt-Molybdenum-Alumina catalysts, Sphericat Nalco 474 and Nalcomo 474 were studied for hydrodesulferization of FMC oil (coal-derived liquid) in a trickle bed reactor. Experimental data were taken at 1500 psig, 2.99 liquid volume hourly space time and 7500 scf Hydrogen/bbl FMC oil for temperatures of 700�F (371�C), 800�F (427�) and 850�F (454�C) using Nalcomo 474 catalyst. Six experimental runs were conducted, the duration of which varied from 100 to 200 hours. An attempt was made for the preliminary assessment of carbon build-up on a catalyst as well as the effect on catalyst activity caused by the amount of H?S supplied during catalyst presulfiding.
