| abstract |
A composition for purifying a liquid, such as used cooking oil, unrefined edible oils, or biodiesel fuel, that comprises at least one purifying material, such, as magnesium silicate, and at least one binder material that is a solid or a semi-solid at room temperature, or is water or a glycol. When the composition is placed in a liquid, and the liquid is heated, the solid composition disintegrates and the at least one purifying material is released in the liquid. Such composition minimizes or eliminates contact with the dust associated with solid adsorbent materials, and provides for a controlled release of the at least one purifying material into the liquid to be purified. |
