Catalytic Degradation of Mixed Plastics over Natural Clinoptilolite Catalysts

摘要

To date, the bulk of the research on the chemical recovery of waste plastics has focused on elucidating the mechanism of degradation for pure polymers [1-3]. Most waste streams, however, contain mixtures of polymers. In addition, a large variety of catalysts studied previously may be unrealistic for practical use due to the high cost of the catalyst. For these reasons, mixtures of PE, PP and PS were selected to study the performance of natural clinoptilolite zeolite (occurring in the Pohang area of Korea) in their degradation.
