Sorbent/ion exchange resin column for pigment removal in recycled TPU
A novel sorbent/ion exchange resin column designed to efficiently remove pigments from recycled thermoplastic polyurethane (TPU) during the glycolysis process, enhancing the quality of recovered polyols for new PU production.
Overview
The sorbent/ion exchange resin-packed column offers a groundbreaking solution for pigment removal in the recycling of thermoplastic polyurethane (TPU). By integrating this column into the glycolysis process, the system efficiently depolymerizes TPU, recovering high-quality polyols and glycolysates while removing unwanted pigments. This innovation not only enhances the recyclability of TPU but also supports the production of new polyurethane materials from recycled components.
Technical specifications
Key features:
- Utilizes a glycolysis process with sodium/potassium acetate catalysts to break down TPU into polyols and glycolysates.
- Operates effectively at temperatures between 200-220°C under atmospheric pressure.
- Incorporates a sorbent/ion exchange resin column with customizable functional groups for optimal pigment filtration.
- Allows optimization of parameters such as catalyst dosage, temperature, contact time, and resin packing density.
- Supports reusability of glycols through distillation and conversion of by-products into high-value materials.
Technology readiness level
This technology has been validated at a laboratory scale, with a Technology Readiness Level of 4. Future studies aim to optimize reaction conditions, sorbent materials, and operational parameters to enhance scalability and efficiency.
