Claims37
A particle suitable for filtration of oils for use in preparation of biodiesel, said particle comprising a substantially inert porous inner particle and at least a partial coating on said inner particle, wherein said coating comprises a non-food grade acceptable polymer comprising an amine group, an imine group, or both.
A method for removing contaminants from used oil, the method comprising the step of contacting the oil with a filtering media, wherein the filtering media comprises a non-food grade acceptable polymer comprising an amine group, an imine group, or both, thereby removing at least some of said contaminants and making said oil suitable for use in preparation of biodiesel.
A particle comprising an inner porous core of diatomaceous earth and at least a partial coating covalently bound via a silane moiety to said porous core.
