Of nine catalysts tested in a fixed-bed pilot unit for upgrading a 50% West Kentucky SRC recycle solvent blend, best desulfurization and deoxygenation activities were obtained with proprietary catalysts, Mobil HCL-2 and HCL-3, American Cyanamid's commercial HDS-1443, and Harshaw's commercial 618X catalyst. The activities depended in part on the presence of macropores. The best Conradson carbon residue reduction was obtained with Mobil HCL-2 and HCL-3, and with Amoco'/s developmental catalyst Amocat 1B. The highest polar asphaltene conversion was obtained with Amocat 1B and HDS-1443. The lowest hydrogen consumption as a function of total liquid product sulfur content occurred with HCL-2, HDS-1443, and Amocat 1A. An aging run with Amocat 1A was operated smoothly for 15 days at 2000 psig and 775/sup 0/F, and then terminated owing to incipient reactor plugging; a simple deactivation equation correctly predicted the degree of desulfurization with time on stream, which was equivalent to a 2/sup 0/ to 3/sup 0/F/day temperature rise for maintaining constant product sulfur levels. The deposits formed on the catalysts were analyzed.
