AP-118 – Catalyst-free Biodiesel Reactions and Post Treatment Using Commercial Polymeric Resins

Biodiesel was synthesized under catalyst-free supercritical methanol reactions using a variety of oils at 250 to 325°C in a 1-liter high-pressure batch reactor. Multiple experiments were performed at 6 to 80 molar ratios of methanol to oil; product samples were then analyzed by titration, and a Gas Chromatograph which monitored conversion of triglyceride by measuring total glycerine. At 300°C and 27 molar ratios, 97% conversion was attained. Following the experiment samples were placed in separatory funnel and the crude biodiesel layer was treated further to remove free glycerine by centrifugation and also with an Amberlite BD10dry which was more effective.
