▎ 摘  要

NOVELTY - Processing phenol-based rectifying kettle residue comprises (i) subjecting the phenol-based rectifying kettle residue by vacuum extracting deep drawing to obtain vacuum extracting and drawing out and vacuum extracting deep drawing kettle residue; (ii) subjecting the vacuum extracting and drawing out by synthesis treatment to obtain phenolic resin; and (iii) carbonizing the vacuum extracting deep drawing kettle residue to obtain the gas phase product and active carbon, or subjecting vacuum extracting deep drawing kettle residue to extraction and crosslinking polymerization to obtain condensed polyaromatic hydrocarbon resin. USE - The method is useful for Processing phenol-based rectifying kettle residue. ADVANTAGE - The method: can convert the residual solid waste of the phenol-based distillation kettle into industrialized products with excellent performance, and is economical while alleviating environmental pressure. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for phenolic resin, is prepared by the method for treating the residue of a phenol-based rectification vessel.
