the oil to more acceptable levels [1]. It is well known that clay minerals can be used to decolorize oils because of its high adsorptive capacity. In other to enhance this adsorptive property, acid activation of clay is the most commonly used technique. This area of clay modification has received enormous interest from various researc h-ers [2 ...
Disclosed is a method suitable for treating used oil to remove contaminants including ash and color contaminants therefrom to provide a purified oil product. The method comprises the steps of providing a porous inorganic membrane module having a high pressure side and a low pressure side, and a body of oil to be treated. The oil is introduced to the high pressure side of the membrane module to ...
