The purpose of this study is to analyze bio-oil composition produced from a low temperature pyrolysis of cooking oils under microwave irradiation. As the feedstock, waste cooking oil (WCO) and fresh cooking oil (FCO) were used. The sample was pyrolyzed at 400°C in a modified microwave reactor with an output power of 900 W. The feedstock was fed into the reactor at 2 ml/min for 60 min under nitrogen gas environment to ensure pyrolysis process. The results showed that the bio-oil compounds of both feedstocks were mainly composed of aliphatic hydrocarbons. Based on carbon number, bio-oil from WCO contained almost 70 wt.% of diesels fraction (C12-C20), slightly lower than FCO which is potential as fuel candidate for diesel engines. © Published under licence by IOP Publishing Ltd.
