Activity of solvent hydrogenation catalyst was investigated from charactarization of recycle solvent in the 150t/d bituminous coal liquefaction pilot plant. The following conclusions are obtained.<BR>(1) In the pilot plant, solvent hydrogenation catalyst exhibits high activity for hydrogenation of aromatic compounds. This activity gives hydrogendonability to recycle solvent.<BR>(2) Recycle solvent mainly consists of tworings aromatic compounds, and increase of more condensed aromatic compounds (over three rings) in the solvent causes decrease of the reaction rate constant.<BR>(3) The reaction rate at the pilot plant is higher than that at PSU and bench scale unit. This results from difference of compositions of the solvents and contacting effectiveness among these facilities. Therefore, it's so important for conceptual design work to evaluate these influences.
