Abstract

Waste oil and grease (O&G) collected from the campus Chick-fil-A restaurant was gravity separated and then chemically transformed from fatty acid into methyl ester (biodiesel) and glycerol. The methyl ester was subsequently extracted and dried from the product mixture. Characterization of the methyl ester (biodiesel) and diesel:biodiesel blends was accomplished using FT-IR, NMR, GC-MS, ICP-MS, thermodynamics via micro-bomb calorimetry, and density and viscosity measurements. Results indicate biodiesel methyl ester composition of approximately 70% methyl oleate and 18% methyl linoleate, consistent with the Chick-fil-A’s use of peanut oil as the primary cooking oil. Fuel blends were then combusted in a diesel generator, exhaust gas captured and analyzed (in progress) to determine composition. Analysis indicates that the biodiesel synthesized from the Chick-fil-A restaurant is suitable for blending with diesel and use as a fuel.
