Catalytic hydrogenation of high volatility bituminous coal and various coal extracts: final report for 1986-1987. SOMED (School of Mines and Energy Development) project. Faculty research report
Model compounds, naphthalene, quinolines, and isoquinoline (possible extracts of coal) were selectively hydrogenated to 1,2,3,4-tetrahydro products by a Ziegler-type catalyst (I) made of cobalt stearate and triethyl aluminum (1:2 molar ratio) in hexane solvent and temperatures as low as 22/sup 0/C and hydrogen pressure of 700-800 psi. It was established that a hydrogen pressure greater than 300 psi is crucial for hydrogenation to occur. The important feature of the Ziegler catalyst is that it works best at low temperatures, moderate pressures, and short reaction times, most unusual for a Ziegler catalyst. A sample of solvent-refined coal (SRC) (less than .9% sulfur) was previously liquefied at 90 degree C and hydrogen pressure of 800 psi in a period of 24 h. In this, a sample of Illinois No. 6 high-volatility bitiminous coal (a high-sulfur coal, 5.8% S) was treated with catalyst (I) under the same conditions as applied for SRC. Analysis indicated a 10% conversion for the high-sulfur coal.
