Catalytic hydrogenation of coal-derived liquids. Interim report, March--May 1976. [Ni-W catalyst]
The investigation of the hydrotreating of COED tar with a nickel-tungsten catalyst showed that this catalyst is an improvement over cobalt molybdate in the production of lighter boiling product, that more lighter boiling product is obtained at the longer residence time and that sulfur removal from the product does not increase as the hydrogen rate is increased. Two runs were made on the hydrotreating of SYNTHOIL with cobalt molybdate catalyst to establish a basis for comparison with other catalysts. One run was completed with a nickel tungsten catalyst giving product boiling slightly lower than that obtained from cobalt molybdate. The hydrotreating of Solvent Refined Coal (SRC) was carried out in both continuous and batch reactors using the synthetic coal oil as a carrier solvent and employing a nickel tungsten catalyst. The higher pressure run gave a better conversion. The work to date on these three feedstocks indicates that temperature is a critical variable and should be maintained in a narrow range. In order to determine more quickly what is the optimum temperature for each catalyst and set of conditions, a few batch runs in a rocking bomb autoclave are being carried out on all three feedstocks prior to running the continuous feed hydrotreaters.
