The effects of two disposable catalysts on liquefaction of lignite were evaluated by comparison of overall conversions and yields of distillate. All experiments were conducted using a tubing bomb reactor at temperatures ranging from 400˚C to 440˚C for a period of twenty minutes.
Using ammonia, a reaction temperature of 420˚C and a reducing gas of either synthesis gas or carbon monoxide gave the maximum yield of distillate. While ammonia promotes the formation of distillate, overall conversion is not increased. Quinoline had no significant effect on the overall conversion and distillate yield, except in the presence of hydrogen at 420˚C.
