A Review on Extraction of Liquid Fuel from Waste Plastic

Abstract

Liquid fuel is a plastic-based derived fuel. A rapid economic growth and consumption of plastic across globe, it creates a negative impact on environment and affects the human health. The consumption trend of natural fossil fuel and other renewable resources indicating that a resources are depleting after a certain decades. Thus, to find an alternative energy to secure the future demand of world. Waste plastic are attractive way to address this problems. This materials are an excess generation over the last 60 years and using this to generate the liquid fuel for many purposes such as transportation, and generating an electric power for urban and rural areas. There are different methods of converting of waste plastic into a valuable fuel so called liquid fuel. These are a catalytic pyrolysis, thermal pyrolysis and hydro cracking pyrolysis. But, pyrolysis is a chemical recycling process that can convert plastics into high quality oil, which can then be utilized in internal combustion engines for power and heat generation. During process, it can be used the catalyst to reduce the reaction temperature, promote decomposition reaction, and improve quality of products. They are factors that affects the production. Among of these are temperature, type of reactor that used, pressure and time. Therefore, according to the literature review, it is possible to produce liquid fuel from waste plastic.
