Summary:The invention relates to the technical field of chemical production, and particularly discloses a GBL heavy component recycling method which comprises the following steps: step S001, collection: collecting GBL heavy components after heavy component removal of crude GBL; step S002, rectification: rectifying the heavy component of the GBL through a rectifying tower; and step S003, recycling: in the process of the step S002, recycling the tower top GBL heavy component rectification liquid before returning to the gasification tower, carrying out rectification operation on the GBL heavy component through the rectification tower, carrying out rectification operation on the GBL heavy component, directly discharging and barreling the rectified tower kettle heavy component as solid waste at regular intervals, and recycling the tower top light component before returning to the gasification tower. The GBL heavy component rectification liquid after rectification basically does not contain coking heavy components, poisoni
