Research Project: EXPANDING THE USE OF FATS AND OILS AS REPLACEMENTS FOR FOSSIL-DERIVED FUELS, LUBRICANTS, AND POLYMERS

Location: Sustainable Biofuels and Co-Products

Project Number: 8072-41000-084-00
Project Type: Appropriated

Start Date: Jan 11, 2010
End Date: Sep 07, 2014

Objective:
Objective 1: [addresses NP 307 Action Plan Problem Statements 3(c)(1), 3(c)(2) and 3(a)(4)] Develop new technologies that enable (1) commercial direct (‘in-situ’) production of biodiesel, and (2) commercially-preferred processes for the production of biodiesel from available, low-cost feedstocks. Objective 2: [addresses NP 307 Problem Statements 3(c)(1), 3(c)(2) and 3(a)(4)] Develop technologies that enable commercially-preferred technologies to remove performance-degrading biodiesel contaminants such as catalysts, sterol glucosides and sulfur. Objective 3: [addresses NP 307 Problem Statement 3(c)(5), and NP 306 Problem Statement 2c] Develop technologies that enable; (1) commercial production of hyperbranched polymer products from byproduct glycerol; and (2) commercially-viable and environmentally benign processes for new high-value industrial products made from fatty acids or the combination of fatty acids and lignin derivatives.

Approach:
Develop technologies to use heterogenous catalysts to replace homogenous catalysts in the synthesis of biodiesel from free fatty acids and from glycerides in low quality feedstocks. Improve and scale-up methods newly develop method for biodiesel synthesis from trap grease. Using chromatographic and spectroscopic technologies, identify the structures of sulfur containing species contaminating biodiesel from low quality feedstocks and develop methods for their removal. Using enzymatic catalysis, remove sterol glucoside contaminants from vegetable oil based biodiesels. Develop new methods for the use of novel solid catalysts to modify fatty acids, in some cases through their combination with lignin degradation products generated by the pyroloysis of lignocellulosic feedstocks, to produce lubricants, personal care materials, and other functional lipids. Develop organic chemical methods to produce prepolymers from biodiesel glycerol and organic di-acids and use these to produce hyper-branched polymers. Determine the size and structures of these and determine their physical properties.
