Coal Liquid derived from NEDOL Coal Liquefaction Process consists of a variety of chemical contaminants such as nitrogen, oxygen, and sulfur. In order to use the coal liquid as transportation fuel, it is needed to improve the quality of coal liquid. Therefore, TOP-NEDOL (Total Oil Processing NEDOL) process in which coal derived liquids were hydrogenated with together solvent at the solvent hydrogenation unit was constructed in PSU. Coal liquefaction test based on the TOP-NEDOL process was carried out using the 1ton/day Process Supporting Unit (PSU). Coal liquefaction and fluid dynamics in the liquefaction reactors were investigated.
