Microwave assisted esterification of acidified oil from waste cooking oil by CERP/PES catalytic membrane for biodiesel production

► We prepared CERP/PES hybrid catalytic membrane for biodiesel production. ► We conducted esterification of acidified oil under traditional heating method. ► We conducted esterification of acidified oil under microwave irradiation. ► Biodiesel production with microwave irradiation needs less time and catalyst. ► Esterification with microwave irradiation offers a fast, easy and effective route.
