A PROCESS FOR PRODUCING BIODIESEL FROM WASTE COOKING OIL

摘要

HETEROGENEOUS PRODUCTION OF BIODIESEL FROM WCO HAS BEEN CONDUCTED USING SRO AS A BASE CATALYST IN TRANSESTERIFICATION REACTION AND FERRIC SULPHATE AS A SOLID ACID CATALYST IN PRE-TREATMENT OF WCO TO CONVERT FFA IN WCO INTO TG. WCO WAS SUBJECTED TO BE PRE-TREATED USING ESTERIFICATION REACTION TO REDUCE THE ACID VALUE BEFORE FURTHER TRANSESTERIFIED TO COMPLETE THE REACTION. THE CONVERSION OF FFA IN WCO IN PRE-TREATMENT, THE EFFECT OF METHANOL TO OIL MOLAR RATIO, CATALYST TO OIL MASS RATIO AND THE REACTION TIME IN TRANSESTERIFICATION WERE INVESTIGATED.
