Apparatus for recovering high-boiling point solvents which comprises: a honeycomb-structured rotor 1 having an adsorbent supported thereon; a separator 3 for partitioning the neighborhood of each end face of the rotor into two regions, adsorption zone 5 and desorption zone 4; fan means F1 that supplies the adsorption zone 5 with air containing a solvent boiling at 150 DEG to 300 DEG C. and which causes part of the clean gas effluent a from the opposite end face of the rotor to be released into the air atmosphere while the remainder is supplied into the desorption zone 4; heating means H for heating the clean gas; cooling means C for separating a solvent enriched gas S into a liquefied product L to be recovered and a cooled lean gas V; and return means F2 for turning the cooled lean gas V back to the feed gas.
