Solvent refined coal (SRC) process. Research and development report No. 53: interim report No. 18, 1975. Development of a process for producing an ashless, low-sulfur fuel from coal. Volume IV: product studies. Part 9: an investigation of the activity of two Cobalt-Molybdenum-Alumina catalysts for hydrodesulfurization of a coal-derived liquid. [M. S. Thesis]
Two Cobalt-Molybdenum-Alumina catalysts, Sphericat Nalco 474 and Nalcomo 474 having bimodal and unimodal pore size distribution respectively, were studied for hydrodesulfurization (HDS) of FMC oil in a trickle bed reactor. Experimental data were taken at 1500 psig, 2.99 liquid volume hourly space time, 7500 standard cubic feet hydrogen per barrel of FMC oil for temperatures of 700/sup 0/F, 800/sup 0/F, 850/sup 0/F using Sphericat Nalco 474 catalyst and for 700/sup 0/F and 800/sup 0/F using Nalcomb 474 catalyst. The experimental system carried out successful operation at 850/sup 0/F for 145 hours. Under the operational conditions of this study, sulfur concentration in the product oils of 0.02 wt% was observed. However, the presence of macropores in Sphericat Nalco 474 catalyst provided no advantage over the micropores alone in Nalcomo 474 catalyst. Both the catalysts maintained their activity during the entire period of operation of a particular run, the duration of which varied from 100 to 200 hours.
