Catalytic hydrogenation of coal-derived liquids. Interim report, March 1980-May 1980
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 well after burnoff. Two different base materials were evaluated with no metal loading. The base materials alone fail to give specification denitrogenation. A study of the fate of the nitrogen removed showed that most of it is in the carbon laydown, lesser amounts in the liquid product and the least in the offgases. Somewhat better operation takes place when the SRC-II feed is preheated to 100 to 200/sup 0/C. A commercial T.C.C. equilibrium petroleum cracking catalyst is not effective in the denitrogenation of SRC-II.
