Abstract

Thermal degradation of nitrogen (N)-containing recycled plastics (styrene-acrylonitrile (SAN), acrylonitrile-butadiene-styrene (ABS)) was carried out in a stirred-batch reactor at 300-400oC under nitrogen stream. The degrada-tion oil began to be generated over 300oC. Recycled SAN plastic was converted to oil with 91.3wt% yield at 380oC,while only 70.9wt% of recycled ABS plastics was converted to oil at the same temperature and both oils containedabout the same 3.7wt% nitrogen as an elemental basis. Rate of oil formation from the thermal degradation of SANwas much higher than that of ABS, but showed a similar degradation pattern in terms of chemical composition. In oilproducts, aromatic contents obtained at 360oC were 70wt% for SAN and 79wt% for ABS, respectively, and decreasedto 59wt% and 57wt% at 380oC with increasing degradation temperature. Dominant product of both degradation oilswas styrene, and the following was ethylbenzene for ABS, but none in case of SAN. Both oils contained the N-contain-ing plastic additives that give rise to a confusion for the identification of authentic N-containing degradation products.
