The Effect of Graphene Oxide Nanoparticles as a Metal Based Catalyst on the Ignition Characteristics of Waste Plastic Oil

Abstract

The alternative fuels were developed from a blended fuel with waste plastic oil and graphene oxide nanoparticles as a metal-based homogeneous combustion catalyst. The alternative fuels were obtained with catalytic cracking of waste plastic of high-density polyethylene. Physical properties of fuel were analyzed and the fuel blends were compared with the properties of commercially diesel fuel. The main compound of waste plastic oil analysis was done with gas chromatography-mass spectrometry (GCMS), and the fuel was characterized using Fourier transform infrared (FTIR) spectrometer. The results show that the addition of graphene oxide as a metal-based homogeneous combustion catalyst success improves ignition performances of fuels. Even though the viscosity and density of the fuel increase but the fuel ignition rate increases. This phenomenon indicates that the existence of graphene oxide has succeeded in increasing the mass of fuel molecules and weakening the bonding force between the carbon chains. Moreover, the results also showed that the addition of graphene oxide success increases the reactivity of fuel molecules thus makes the fuel easier absorbing heat and ignite.
