Abstract: “The transesterification of waste cooking oil (WCO) is studied extensively. The efficiency and economical operation of bio fuel production depend on the ease of operation and cost control. Co-solvent hexane can reduce the time of reaction and enhance the recovery of an ester. Reaction, solvent recovery, and product separation are done in many steps. Reactive distillation offers an efficient and economical method of production of bio diesel. This research paper deals with optimizing reactive distillation parameters for co-solvent transesterification of WCO.”

Keywords: Reactive distillation, Transesterification, Co-solvent, Solvent recovery, Waste cooking oil and Bio diesel.
