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 pure water nylon waste pyrolized oil percentage yield obtained was 63% without application of the catalyst while the pyrolyzed oil obtained utilizing (CaOH)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
