Title: Catalytic hydrogenation of coal-derived liquids. Interim report, December 1981-February 1982

Abstract

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 occursmore » in the 115 to 161A range, and that activity decreases as median pore diameter goes below 90A or above 160A.« less
