- Cracking, hydrocracking and hydrotreating catalysts were prepared and tested for activity on a 337 to 700/sup 0/F SRC-II Fuel Oil Blend and hydrogenated products from this feed material. Sixty-five cracking catalysts were prepared and activity tested at two different temperatures (900 and 1000/sup 0/F) on two different feeds (SRC-II Fuel Oil Blend: as is, 8.7 wt % hydrogen, and hydrogenated, 11.0 wt % hydrogen). With the hydrotreated SRC-II Fuel Oil Blend corrected conversions of 430/sup 0/F+ feed of 68 to 75 wt %, C/sub 5/-EP gasoline product distribution of approx. 50 wt %, and coke makes of 4 to 9 wt % were obtained at 900/sup 0/F with catalysts composed of broad pore volume distribution matrix binder components and active exchanged Y-zeolites. When the same catalysts were tested on the unhydrotreated SRC-II Fuel Oil Blend, conversion and gasoline in the product were much lower (37 to 39 wt %, and 18 to 20 wt %, respectively) and coke was (8 to 14 wt %). Thirty hydrocracking catalysts were prepared and activity tested on hydrotreated SRC-II Fuel Oil Blend. Three series of bi-functional catalysts containing low-sodium cracking bases such as hydrogen and rare earth exchanged ultrastable Y-zeolites (US-Y), and exchanged or metal substituted Synthetic Montmorillonite Micas (SMM's) containing Group VIB and/or Group VIII hydrogenating metal components were prepared and tested. One hundred hydrotreating catalysts were prepared and activity tested continuously under the same conditions used for hydrocracking activity testing. None of the exploratory catalysts tested were quite as good as the commercial Filtrol HPC-40 for HDN (85% maximum vs 88% for HPC-40). The HDS results were similar for the best exploratory and commercial catalysts (94 to 96%).
