Introduction

1. Sponsored by The National Science Foundation Grant ID No.: DUE-0756921 Transesterification equation The authors of this poster would like to thank several people. Our work would not have been possible without the aid of: Dr. Mingming Lu Yang Liu QingshiTu Dr. UrmilaGhia Kristen Strominger The University of Cincinnati The National Science Foundation Introduction The objectives of this project were: To study the production of biodiesel in waste cooking oil (WCO) and in waste coffee grounds (WCG) To examine biodiesel as a practical energy resource To investigate the effects of variations in reaction times during WCO extractions To determine the effects of using various WCG mixtures (5% NaOH, 5% KOH, and 10% KOH) Objectives Waste coffee grounds (WCG) 1. Weigh out coffee grounds 2. Combine with methanol 3. Allow reaction to proceed for 2.5 hours, taking samples every 30 minutes Materials and Methods Conclusions Relationships determined from the WCO data: • The longer the reaction time, the higher the percent recovery of biodiesel and the less time required for separation Glycerol yield with different reaction times during WCO extractions remained relatively constant WCO and WCG extraction purity to be determined Need to continue research on lowering cost production of biodiesel for both WCO and WCG production methods Acknowledgements Production of Biodiesel from Waste Feedstocks Data and Results Anna Greve and KathePocker Under the Advisement of Dr. Mingming Lu University of Cincinnati, Cincinnati, OH During this project, biodiesel was produced from: Waste cooking oil (WCO) 1. Perform titration and calculation 2. Combine MeOH and NaOH 3. Stir and heat WCO, MeOH, and NaOH for various times 4. Allow solution to settle 5. Separate biodiesel and glycerol WCO Separations Rotary Extractor for WCG Materials and Methods WCO and WCG Production Procedures In today’s world, there is a high demand for diesel fuel. There are several problems associated with traditional energy sources such as: Pollution Foreign dependency Nonrenewable resources Biodiesel solves several of these problems: Produces fewer air pollutants and harmful greenhouse gases Renewable, domestically produced resource Utilizes otherwise problematic waste products References Al-Hamamre, Zayed, SaschaFoerster, Franziska Hartmann, Michael Kroger, and Martin Katlschmitt.
