  1. Heterogeneous Catalysts for Biodiesel Production Chemistry & IfM Louisiana Tech University • Presenter: UpaliSiriwardane • Date: November 5, 2009

  2. Summary Statement • Bottom line: Renewable energy source and cost effective alternatives to replace petro-diesel. • Develop heterogeneous to replace homogenous catalysts to minimize waste water and produce value added pure glycerol. • Develop a bench scale biodiesel reactor incorporating characteristics of heterogeneous catalysts

  3. Research Context and Prior Work Preparation ,characterization and optimization of catalysts • Fisher-Tropsch (FT): Hydrocarbons from syngas. 2000-2004:"Novel Preparations and Magneto Chemical Characterization of Nanoparticle Mixed Alcohol Catalysts" Department of Energy, National Energy Technology Laboratory. • Water-gas-shift (WGS): Hydrogen from water and CO 2006-2009: “Development of Low Cost Membranes (Ta, Nb, and Cellulose Acetate) for H2/CO2/CO Separation in WGS Reactors,” Department of Energy, National Energy Technology.

  4. Questions to be Addressed Heterogeneous biodiesel catalysts Type of active catalysts: acid/base etc. Type of catalyst support system: alumina etc. Type of synthetic procedure: impregnation etc. Techniques for determining efficiency of conversion: GC, HPLC etc. Life-time of the heterogenous catalyst: Turnover Frequency Regenerating procedure for catalysts Effect source of oils on catalytic activity: Vegetable/Fish

  5. Accomplishments to Date • Complete literature survey on biodiesel production. • Identification of active catalysts: Metal Oxides • Synthetic procedure to trap active catalyst on support systems: sol-gel/hydrothermal methods. • Techniques for determining efficiency of biodiesel conversion: GC analysis (FAME). • Catalysts characterization techniques: DTA/TGA, BET surface area, PXRD, SEM, AFM and TEM.

  6. Plans for 2009-10 Preparation of nanoparticle metal oxide: MxOy incorporated on supports ( Al2O3, Al2O3/SiO2 and DLH (double-layered-hydroxides) Mg/Al, Zn/Al. Selection and optimization of heterogeneous catalysts system: GC analysis (FAME). Development of Stainless steel bench scale heterogeneous biodiesel reactor system: Incorporation of selected catalyst

  7. Value Proposition • Heterogeneous biodiesel production systems are still under investigation: there is no standard technology. Heterogeneous system will replace the homogenous systems. • Heterogeneous system is less polluting and yield less contaminated biodiesel and glycerol: more economical since extra steps to clean biodiesel is not necessary. • Heterogeneous system could be adopted to various types of oils: veg-oil/ fish-oil/ animal-fat and spent cooking oil
