DENITROGENATION OF ACRYLONITRILE-BUTADIENE-STYRENE COPOLYMER
1. IntroductionRecycling of waste electric and electronic equipments (WEEE) polymers has drawn much attention recently. The conversion of waste plastics into chemical fuel or feedstock represents a sustainable way for the recovery of the polymeric waste. However, in the process of recycling of acrylonitrile-butadiene-styrene (ABS) copolymers, which is a widely used polymer in electric and electronic industry, thermal degradation will produce HCN, Nox as well as complicated nitrogen-containing organic compounds that will not only cause environmental pollution but also cause the produced liquid to fail as fuell. Therefore the denitrogenation of WEEE plastics is a must for this process. Hydrothermal methods2were adopted for denitrogenation, but the denitrogenation effects are still unsatisfying. Moreover, relative high temperatures and pressures are needed, which requires the use of expensive facilities. Therefore, the development of highly efficient denitrogenation of ABS under mild conditions is an area of considerable importance. In this paper, ABS is treated using poly (ethylene glycol) (PEG) as a phase-transfer catalyst. High denitrogenation efficiency has been obtained under mild reaction conditions.
