ABSTRACT:
Used frying oils are regenerated and made suitable for reuse by treating the used oils with a composition consisting of a mixture of activated clay or magnesium silicate with a gel-derived alumina. The treating composition contains from about 15% by weight to about 75% by weight gel-derived alumina, balance activated clay or magnesium silicate. Treatment with the composition significantly reduces the free fatty acid content of the used oil with simultaneous improvement in color and other important properties thus resulting in a purified oil of substantially extended service life.
