Pyrolysis Recovery of Waste Shipping Oil Using Microwave Heating

This study investigated the use of microwave pyrolysis as a recovery method for waste shipping oil. The influence of different process temperatures on the yield and composition of the pyrolysis products was investigated. The use of microwave heating provided a fast heating rate (40 _C/min) to heat the waste oil at 600 _C. The waste oil was pyrolyzed and decomposed to form products dominated by pyrolysis oil (up to 66 wt. %) and smaller amounts of pyrolysis gases (24 wt. %)and char residue (10 wt. %). The pyrolysis oil contained light C9–C30 hydrocarbons and was detectedto have a calorific value of 47–48 MJ/kg which is close to those traditional liquid fuels derived fromfossil fuel. The results show that microwave pyrolysis of waste shipping oil generated an oil product that could be used as a potential fuel.
