Catalytic hydrogenation of coal-derived liquids. Interim report, December 1981-February 1982
The optimum relationship between temperature and space velocity for the 4% CoO, 8% MoO/sub 3/, 1% NiO, 8% WO/sub 3/ MSU catalyst for upgrading SRC-II proved to be 425/sup 0/C and 0.5 SV, best yield; 475/sup 0/C and 0.75 SV, highest naphtha yield; and 500/sup 0/C and 1.25 SV, greatest denitrogenation. The octane number of the 40 to 205/sup 0/C gasoline from the 500/sup 0/C and 1.25 SV run is 90.3. Increasing the operating pressure from the usual 1100 psi to 2000 psi at 425/sup 0/C and 1.25 SV had a beneficial effect on denitrogenation and liquid yield but virtually no effect on desulfurization. The investigation of partially hydrogenated Koppers creosote oil as a hydrogen donor agent was begun with one hydrogenation of the creosote having been completed. The effect of adding 1.5% water to the feed SRC-II to attain specification grade denitrogenation with Harshaw HT-400 catalyst was reported by us previously. When this procedure is applied to the MSU 4% CoO, 8% MoO/sub 3/, 8% WO/sub 3/ catalyst, it again improves the denitrogenation. A study of desulfurization of SRC-II with five different base materials having median pore diameters ranging from 90A to 220A indicated that the highest activity occurs in the 115 to 161A range, and that activity decreases as median pore diameter goes below 90A or above 160A.
