Development of new catalysts for coal liquids refining. Seventh quarterly report, 1 July 1980 - 30 September 1980
Sixty exploratory cracking catalysts formulated with exchanged Y-zeolites, synthetic montmorillonite mica, and various matrix binder components have been activity tested (900/sup 0/F and 1000/sup 0/F, 16 WHSV, 3 Cat./Oil) on SRC-II Fuel Oil Blend (hydrotreated to 11.0 wt. % hydrogen). To date maximum corrected conversions of 70 wt. %, and C/sub 5/-EP gasoline product distribution of 50 wt. % have been obtained at 900/sup 0/F with catalysts composed of various matrix binder components, and final catalyst rare earth concentrations of approx. = 5 wt. %. Bifunctional hydrocracking catalysts containing reduced noble metal hydrogenating components, and a low sodium ultrastable Y-zeolite cracking base formulated into extrudates with ..gamma..-alumina have proved active with hydrotreated SRC-II Fuel Oil Blend (11.6 wt. % hydrogen, 0.10 wt. % nitrogen, 0.03 wt. % sulfur). Corrected conversion and C/sub 5/-EP gasoline product ranged from 62 and 55 wt. % respectively at 8 hours reaction time, to 46 and 51 wt. % respectively after 16 hrs. reaction time with the above described platinum metal catalyst, (reaction conditions: temperature 750/sup 0/F; H/sub 2/ flow rate, 5000 SCF/bbl; LHSV, 1 ml oil/ml cat-hr; H/sub 2/ pressure, 1000 psig). Alumina and silica-alumina catalysts impregnated with MoO/sub 3//NiO and the additional promoters P/sub 2/O/sub 5/, ZnO and MnO were activity tested (same conditions as above) for HDN and HDS with the as is SRC-II Fuel Oil Blend. The most active catalyst, 100% Kaiser SA promoted with P/sub 2/O/sub 5/ afforded, 85% HDN, and 96% HDS after 24 hours on stream. The complete series of metal substituted SMM catalysts, impregnated with MoO/sub 3/, and compounded with 33 wt. % Kaiser SA alumina to improve their porosity, has now been activity tested as above. The results indicate maximum HDN activity of 60-62% with MoO/sub 3/ on Ni-substituted SMM, and maximum HDS of 91-92% with MoO/sub 3/ on Co-substituted SMM.
