Topics covered in Advanced Topics class:

• working with high-free-fatty-acid oil
• working with high-water feedstock
• acidulating glycerin and wash water for easier disposal and cost savings
• testing biodiesel, glycerin, and wash water for soap
• producing biodiesel from oils recovered from glycerin
• acid-catalyzed etherification options
• methanol recovery from biodiesel (GL-1 process) and glycerin.
• using glycerin as a solvent in various stages of the process

There will be an extensive hands-on section of the class devoted to techniques for making biodiesel using ethanol instead of methanol, and we will discuss small-scale fuel ethanol production.

We will also discuss water-free soap removal such as the use of the GL-1 process and ion exchange resins.
