PROCESS METHOD FOR ADSORPTION AGENT FROM THE PYROLYSIS RESIDUE OF WASTE POLYSTYRENE

摘要

A method of manufacturing adsorber is provided to recycle pyrolysis residue obtained thermally decomposes waste polystyrene as a raw material of the adsorber, to reduce environment contamination problem by waste, to secure steadily the raw material of the adsorber and to save a production cost. A waste polystyrene melt is injected in a pyrolysis reactor and a styrene monomer and a pyrolysis residue are manufactured at 350 ~ 400 °C. The manufactured pyrolysis residue is heated at 900 ~ 1000 °C under an inert atmosphere and separated into a volatile component and a solid carbide. The solid carbide perform an activation reaction at 900 ~ 1000 °C by an oxidative gas.
