Magnidon+ removes both soaps and sterol glucosides from biodiesel
Recently Environ Fuels of New Zealand succesfully applied Magnidon+, Biodys activated bleaching earth compound, for biodiesel purification. Magnidon+ did not only prove to remove soaps and neutralize catalyst succesfully, but also removed the feared sterol glucosides which lead to high FBT levels. Environ Fuels has been using magnesiumsilicate and diatomite to achieve both removal of soaps and glucosides in the recent past, but decided to retire both these products in favor of Magnidon+ last month.
Sterol glucosides (SG’s) are present in some vegetable oils. They are not soluble in water and cannot be removed easily by traditional methods like filtration or centrifugation. The presence of SG in biodiesel may cause filter blockage at temperatures above the cloud point. Cold temperatures are likely to exacerbate the negative impact of the presence of SG in both pure biodiesel and biodiesel blends.
