Characterization of Pyrolyzed Oil from Disposable Low-Density Polyethylene Sachet Water Nylon Waste Utilizing Calcium Hydroxide Waste [Ca(OH)2] Catalyst

Abstract

The sachet water nylon (popularly known as pure water nylon) waste was pyrolyzed using batch reactor at a temperature of 500°C and  atmospheric pressure. The sachet water nylon waste pyrolized oil percentage yield obtained was 63% without application of the catalyst  while the pyrolyzed oil obtained utilizing Ca(OH)₂ catalyst was found to be 80% and the pyrolyzed carbon black (PCB) was found to be 0%  while the remaining % was mainly pyrolyzed gas. The calorific value of waste nylon pyrolyzed oils was found to be 41.7-42.1MJ/Kg while  the density and viscosity were 0.79-0.82 g\cm3 and 2.9-3.2Cst respectively. The results obtained from the Gas Chromatography Mass  Spectrometer (GC-MS) revealed total of 100 compounds pyrolyzed oils from both catalyzed and uncatalyzed pyrolysis process. More so,  many compounds found to be common in both catalyzed and uncatalyzed pyrolyzed oils.
