CATALYST FOR RECYCLING MONOMER FROM DISUSED PLASTIC OF POLYETHYLENE ORIGIN

摘要

PURPOSE: A catalyst that can increase recover rate of monomer and accelerate pyrolysis rate in case of recycling monomer from disused plastics such as polystyrene, polymethylmethacrylate with reduced coking is provided. CONSTITUTION: In case of recycling monomer from disused plastics such as polystyrene, polymethylmethacrylate, the catalyst is characterized in that as a means to increase monomer recovering rate, BaO support alumina and solid basic catalyst containing MgO and ZnO are used.
