1. Composition and Properties of Tonghua Terpene Resin Understanding the composition and properties of Tonghua terpene resin is essential for effective recovery. Primarily composed of terpene compounds, this resin is derived from petroleum refining processes, where these compounds are isolated and processed into resin products. Due to its unique chemical structure and physical properties, Tonghua terpene resin is widely used in coatings, adhesives, plastics, and other fields. as its applications expand, annual industrial consumption has increased, exacerbating resource depletion. Thus, efficiently recovering Tonghua terpene resin from waste synthetic materials has become an urgent challenge.

2. Traditional Recovery Methods Traditional methods for recovery fall into two categories: physical and chemical approaches.

• Physical Methods: These involve separating the resin from waste liquid or solids through heating, distillation, or other mechanical means. While simple to implement, these methods often require significant energy input and offer low separation efficiency.
• Chemical Methods: Leveraging differences in chemical reactivity between components, these methods use specific reactions to isolate the resin. Though effective for high-purity recovery, they typically demand harsh reaction conditions and complex processes.

3. Emerging Nano-Adsorption Technology With advancements in nanotechnology, nano-adsorption has gained attention as a novel recovery method. Nano-adsorbents, due to their unique surface properties and large specific surface area, can selectively adsorb impurities from Tonghua terpene resin, enabling efficient separation. Additionally, these adsorbents can be reused, reducing production costs. challenges remain, such as optimizing adsorbent selection and regeneration.

4. Innovative Recovery Processes Researchers have explored innovative techniques to enhance recovery rates and purity:

• Additive-Assisted Separation: Introducing specific agents alters the solubility of the resin, simplifying separation.
• Microwave-Assisted Chemistry: Accelerates reaction rates and selectivity, shortening processing time.
• Continuous Operation: Streamlining workflows reduces energy consumption and human intervention.
