As the amount of waste generated increases every year, the importance of recycling waste is increasing day by day. In this situation, recycling waste plastic is very meaningful. Waste plastic treatment technologies include thermal recycling, physical recycling, and chemical recycling. This study developed a low-cost process for adsorbing Cl generated from chemical recycling into red mud, a waste resource, to produce pyrolysis oil. This study achieved four research goals: red mud characterization, adsorbent preparation, real-time Cl measuring device construction, and performance evaluation.
This study also has the meaning of solving the problem of high cost of pyrolysis oil production. Pre-treatment at 700℃ is costly. As a result of literature review, the reduction temperature of Fe-based catalysts decreases when synthesized with Cobalt. Therefore, as a result of impregnating with cobalt, red mud''s reducibility was improved, and the reduction temperature could be lowered by 150℃. As a result of XRD analysis of fresh red mud reduced at 700℃, it was only Fe3O4 phage, but after impregnation with Cobalt, it was confirmed that it was converted to Fe metal phage at 550℃. confirmed an increase. Therefore, it was confirmed that Cl2 adsorption was possible with the waste red mud.
