Method for converting polychlorinated biphenyl oil into a resource, agent for decomposing polyschlorinated bipheny oil, and reclaimed material

The method for converting polychlorinated biphenyl oil into a resource, including chemical decomposition treatment, pelletizing treatment, and thermal decomposition treatment,

• wherein said chemical decomposition treatment chemically converts said polychlorinated biphenyl oil into powder containing a metal salt and prevents the working environment from being contaminated by said polychlorinated biphenyl oil during said thermal decomposition treatment,
• said pelletizing treatment works the powder produced by said chemical decomposition treatment into pellets as pretreatment of the thermal decomposition treatment, in order to prevent the powder from blowing away and facilitates its handling during the thermal decomposition treatment, and
• said thermal decomposition treatment loads the pellets obtained by the pelletizing treatment together with glass cullet into a melting furnace with coke as the fuel and both are melted in said melting furnace at a temperature above the thermal decomposition temperature of the polychlorinated biphenyl oil, so that said pellets are melted and integrated with the glass to obtain slag which is then cooled for reuse as solid substances.

A decomposing agent for polychlorinated biphenyl oil, including calcium oxide whose surface is coated with a vegetable oil and quartz porphyry powder.
