Catalytic hydroliquefaction of North Dakota lignite part I. Effects of process variables on product distribution

Finely ground North Dakota lignite slurried in anthracene oil was hydrogenated in a continuous stirred tank reactor in the presence of a cobalt-molybdenum catalyst. Effects on product distribution of process variables such as H₂ pressure, temperature, space time, lignite concentration in anthracene oil, and catalyst concentration have been investigated. Results indicate that 80% of maf lignite can be converted into gaseous and liquid products with an oil yield of about 35% on the same basis.
