Abstract

Catalytic dissociation reaction was studied in order to transform waste plastics to oil by using noble metal supported catalysts. XRD, SEM, and GC/MSD analysis were performed to find the crystalline structure and shape, and product distribution. Generally, dissociation reaction occurs at low temperature compared to pyrolysis. Dissociation reaction has advantage of gasoline yield with respect to pyrolysis which products mainly C1~C4. The result of dissociation reaction, gasoline was obtained much as a product. C5~C11 compounds were produced as a gasoline product on Pt-zeolite among noble metal catalysts at 340 oC. The conversion of dissociation reaction of waste plastics on the prepared catalyst was above 70% over 340 ℃.
