Abstract

Two runs of more than 100 hours of catalyst life were completed using SRC-I and SRC-II as the feeds. One run had catalyst regeneration every three hours, the other every eight hours. The catalyst, 4% CoO, 8% MoO/sub 3/, 1% NiO and 8% WO/sub 3/ on NALCO-78-6008C alumina base, reduced the nitrogen content to less than 0.3% and showed no signs of deterioration in activity. Regeneration after the three or eight hour periods was by burnoff with oxygen in nitrogen followed by re-sulfiding with H/sub 2/S in hydrogen. The liquid yield from SRC was 90% of which 30% was 50 to 204/sup 0/C. boiling range gasoline. It appears that a viable process to convert SRC into a feedstock acceptable to a petroleum refinery has been discovered. A study of the effect of carbon laydown on pore volume and subsequent deactivation of the catalyst was carried out in a pressurized batch reactor. Little reduction in pore volume was noted. Three commercial catalysts, Harshaw HT400, NALCO MO477 and NALCO MN502, were evaluated with SRC-II. These catalysts are capable of giving specification grade denitrogenation for up to five hours. The effect of added water to the feed stream lengthened the cycle time formore »« less

Catalytic hydrogenation of coal-derived liquids. Interim report, June-August 1981

Technical Report Berg, L; McCandless, F

The development of special catalysts to convert SRC-II into a feedstock acceptable to a conventional petroleum refinery proceeded with the carrying out of several long-cycle runs. A catalyst comprising 4% CoO, 8% MoO/sub 3/, 1% NiO and 8% WO/sub 3/ on NALCO base 78-6008 was operated for 102 hours with burn-offs and resulfiding every three hours. The same catalyst was operated for 104 hours with regneration every eight hours. This catalyst was then operated for runs of 60, 100 and 300 hours with no burn-off. Harshaw's HT400 with 15% MoO/sub 3/ and 3% CoO was operated for a single cyclemore »« less
Upgrading solvent refined coal by catalytic hydrotreatment

Thesis/Dissertation Yeh, A

Catalytic hydrotreatment was performed to upgrade SRC-II Vacuum Flash Feed (VFF) and Light Ends Column Feed (LECF) which were produced from the Pittsburg and Midway Coal Mining Company's SRC-II pilot plant. The liquid products were analyzed for sulfur and nitrogen content. The distillation yields were also determined. The statistical studies on the metal effects showed that Co, Mo, and W significantly increased the catalyst activity for the denitrogenation of both SRC-II coal liquids. The adding of Ni appeared to be ineffective. The effect of Co and Mo on the desulfurization of LECF was positive. The interaction between Co and Momore »« less
Catalytic hydrogenation of coal-derived liquids. Interim report, March 1980-May 1980

Technical Report Berg, L.; McCandless, F.

The work on the development of catalysts capable of converting solvent refined coal, SRC-II, into a feedstock suitable for a conventional petroleum refinery was continued. This requires a process which reduces the nitrogen content from the 1.17% in SRC-II to at least as low as 0.3%. A catalyst containing MoO/sub 3/, CoO, NiO and WO/sub 3/ was evaluated, subjected to an air burnoff to remove the carbon laydown and re-evaluated. It gave acceptable denitrogenation and desulfurization. Two catalysts containing only MoO/sub 3/ and CoO were fabricated and evaluated both before and after burnoff with air. They did not perform wellmore »« less

Technical Report Berg, L; McCandless, F

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 virtuallymore »« less
Catalytic hydrogenation of coal-derived liquids. Interim report, September-November 1981

Technical Report Berg, L; McCandless, F

An experimental study was completed to determine the optimum relationship between temperature and space velocity for our hydrotreating-hydrocracking catalyst developed for the denitrogenation of Solvent Refined Coal (SRC-II). The temperature range was 350 to 500/sup 0/C, LHSV was 0.25 to 2.5 and the throughput was held constant at 4500 ml/60 ml of catalyst. The surprising result is that 500/sup 0/C and 1.25 LHSV is the best condition. Conditions were finally found under which a commercially available catalyst will give acceptable denitrogenation of SRC. It is Harshaw's HT400 E 1/32'' and the unique factor is to add 1.5 volume percent ofmore »« less
