Recycle experiments of coal-liquefaction and solvent-hydrogenation were carried out with a 5L batch-autoclave test unit in order to optimize the process variables. The followings are obtained; (1) Lower solvent-to-coal ratio in the feed slurry gives higher aromatic carbon fraction (fa) and higher concentration of heavy fraction in the recycle solvent. (2) Higher solvent-hydrogenation severity gives lower fa and lower concentration of heavy fraction in the recycle solvent. (3) The combination of lower solvent-to-coal ratio in the feed slurry and higher solvent-hydrogenation severity presumably control the recycle solvent properties and advance the process efficiency.
