The recycling of transformer oil by selective desulfurization could be achieved by using thesorbent bearing copper. In this paper, a novel carbon-based nano-copper material was designed andprepared with chitosan as copper dispersant. By the complexation between various functional groupsand copper, the material with high copper load can be obtained, which could avoid poor bulk copper.This research focused on the role of chitosan in copper dispersion regularity, analyzed the effect ofdesulfurization and regeneration process on the physical and chemical properties of transformer oil, re-vealed the relationship between structure, composition and desulfurization effect and studied the ad-sorption desulfurization mechanism with the hope to realize the rational design and controllable prepa-ration of nano-copper materials with high desulfurization efficiency. The result is not only of great sci-entific significance and important theoretical value for the research and development of new high effi-ciency desulfurization adsorbent, but also of important application value for accelerating the commer-cialization process of transformer oil regeneration.
