Microwave pyrolysis of scrap tires and its pyrolysis oil performance in diesel engine

Microwave assisted pyrolysis of scrap tires allows recovery of energy and useful materials, such as pyrolytic oil, char and gases. Scrap tire were being heated in inert atmosphere at temperature between 400 and 600 °C to produce liquid fuel. In this study, a modified conventional microwave and equip...
