For anyone interested in the continuing saga of refining techniques for cleaning the free fatty acids out of waste vegetable oil, I have new results. Micro-Cel T49 is a synthetic calcium silicate from Celite Corporation (rep is Seegott:)
http://www.seegott.com/companies/celite.html It's intended for adsorbing FFA's from edible oil in the fryer oil filtration units, and also on a commercial scale. It's physically much like talcum powder (talc is magnesium silicate), and absorbs 70% of its weight in FFA's. Then you have to filter it out. I added 15 g. of Micro-Cel to a liter of WVO which titrated at 1.6, warmed it in the microwave, stirred it a bit, let sit for half an hour, and filtered 100ml or so thru a coffee filter -- titration was now 0.5 ml !! Pretty simple.....now to build a proper filtration tray. Oh, BTW, the stuff is not cheap -- about $2.50 USD per pound in 50 lb bags. A helluva lot easier than refining with lye, tho. ------------------------ Yahoo!
