97/00915 Liquefaction of commingled waste plastics containing PVC

Abstract

Direct liquefaction studies were conducted on a washed, commingled waste plastic (CWP), as received from the American Plastics Council and after addition of 5 wt.% of polyvinyl chloride (PVC). Both non-catalytic and catalytic experiments were performed the catalytic experiments utilized 1 wt.% of HZSM-5. The experiments on the CWP-PVC mixture were conducted with and without the addition of 5 wt.% of calcium hydroxide. The effect of PVC on product yields was evaluated. Oil quality was examined by GC simulated distillation. The forms of occurrence of chlorine in the liquefaction products were determined by x-ray absorption fine structure (XAFS) spectroscopy utilizing the X-ray absorption near edge structure (XANES).
