Effect of catalyst acidity on the hydrogen-donor content of a hydrotreated coal liquid
Nine catalysts were used to hydrotreat a coal-derived distillate in a fixed bed reactor. These catalysts were prepared from a variety of different support materials and exhibited a wide range of surface acid site densities. Liquid produce was collected in each run after approximately 200 h on stream...

| description | Nine catalysts were used to hydrotreat a coal-derived distillate in a fixed bed reactor. These catalysts were prepared from a variety of different support materials and exhibited a wide range of surface acid site densities. Liquid produce was collected in each run after approximately 200 h on stream and analyzed by /sup 1/H and /sup 13/CNMR methods for estimating the fraction of donatable hydrogen. The results suggest that hydrogen-donor content decreases with increasing catalyst acidity, probably because the acid sites catalyze isomerization and cracking reactions. It is suggested that some benefit could be derived in coal liquefaction process by employing low acidity catalysts. |
