Adsorption Odors of Oil Product from Waste Plastics with Activated Carbon

Abstract

The aim of this research is improve odors of fuel oil from pyrolysis of high density polyethylene plastic wastes from drinking water bottles. Activated carbons in form power and extrude were used to adsorbed compound which produced odor of pyrolytic oil. In the experiment, the comparisons of three activated methods such as: activated by heating, activated by 60% wt nitric acid and activated by 60% wt potassium hydroxide. The results were shown that the extrude activated carbon with nitric acid had less odor of oil products, properties of their such as viscosity, flash point and distillation followed the diesel standard of  Department of Energy Business. Chemical compositions of selected 5 oil samples were analyzed by Gas Chromatography Mass Spectrometry (GC-MS) had carbon atom range C₁₄-C₁₉ for 27.79% and disappear hydrocarbon compound of odor of pyrolytic oil such as ketone, alkyne, cycloalkane cycloalkene and alcohol.
