Low-Temperature Activated Carbonization for Reuse of Waste Photoresist
■ Technology Overview
• Waste photoresist consists of solvents and resins. The resins wastes are currently being treated by incineration and cause foul-smelling exhaust gases
• Resin is a good carbon source material. We developed low temperature activated carbonization for the waste photoresists and converted it into activated carbon material for reuse
■ Core Technology
• Use metal halide catalyst: resin/fiberglass cloth fixation enhancement
• Catalyst/resin formulation design: ≤400℃ carbonization process
• Continuous impregnation & carbonization line: production test
