Two Novel Approaches Used to Produce Biodiesel from Low-Cost Feedstocks

摘要

The price of feedstock is one of the most significant factors affecting the economic viability of biodieselmanufacturer. Many approaches were investigated to reduce the biodiesel production cost. The present work gave apreliminary study of two approaches to economically produce biodiesel from waste cooking oil (WCO) and flakedcottonseed. One was the use of ultrasound-assisted synthesis of biodiesel from WCO. The other was the application of insitu transesterification from flaked cottonseed. Gas chromatography (GC) and High performance liquid chromatography(HPLC) results demonstrated the feasibility of using both approaches to produce biodiesel from low-cost feedstock.
