In this report, the pilot plant studies on the refining of two H-Coal syncrudes are summarized. This report shows that conventional transportation fuels (jet, diesel, and motor gasoline) can be refined from the H-Coal syncrudes. These syncrudes are relatively low boiling when compared to petroleum. As a consequence of this property, excellent yeilds of distillate fuels (jet and diesel) can be obtained from the syncrudes by simple hydrotreating with no subsequent cracking process. For the exclusive production of gasoline, a cracking process is needed. Hydrotreating and, when necessary, hydrocracking appear to be suitable refining routes for converting the coal-derived syncrude to transportation fuels. This route gives a yield of transportation fuel almost equivalent to the original volume of the syncrude. In addition, the heteroatoms are ultimately removed as sulfur and salable ammonia. The pilot plant studies have shown that modern commercial hydroprocessing technology can be used to refine the H-Coal syncrudes. However, they also show that high boiling impurities in the syncrudes can make these feedstocks difficult to refine in the downstream hydroprocessing units. Most of these impurities can be removed by redistilling the syncrude.
