Characterization of the Heavy Cut Oil Extracted from the Hydropyrolytic Depolymerization of LDPE, LLDPE, MDPE and HDPE type of Polyethylene Mix

Abstract

polyethylene waste has become one of the major pollutant worldwide. The conversion of the polyethylene waste into useful hydrocarbon products is being studied and investigated. The conversion of the LDPE, LLDPE, MDPE and HDPE type of polyethylene into hydrocarbon products via hydropyrolysis process is carried out. The product comprises of the gaseous and the liquid products. The liquid or the mother liquid product comprises of the naphtha, middle distillate and the heavy cut oil of varied characteristics. The heavy cut fraction is the part of the mother liquid which remains as the semi liquid fractionate. The heavy cut fraction is the part which is difficult to extract by the fractional distillation under atmospheric pressure. Thus this part remains at the bottom of the distillation column. The characteristic property of the heavy cut oil is studied and it is found to be important as it generates a structure with a higher molecular weight that is less easily volatilized.The heavy cut oil extracted from polyethylene mix has temperature grater than 370 C. Simulated distillation analysis and the mass spectra analysis were carried out to understand the thermo chemical and the structural properties of the heavy cut oil or end use.
