Abstract

A method for pretreating a slurry containing a ruthenium catalyst for use in the continuous partial hydrogenation of monocyclic aromatic hydrocarbons is disclosed. In this method, the above-mentioned slurry is heat treated at a temperature of from 60 to 180 °C for at least 10 minutes while agitating. By using the pretreated catalyst slurry in the above-mentioned continuous partial hydrogenation, partial hydrogenation reaction products can be efficiently obtained without suffering from the excess mixing of the components of the catalyst slurry into an oil phase containing the partial hydrogenation reaction products, thereby enabling operations and facilities required for separation to be simplified.
