See full text

A method of refining a natural oil includes: (a) providing a feedstock that includes a natural oil; (b) reacting the feedstock in the presence of a metathesis catalyst to form a metathesized product that includes olefins and esters; (c) passivating residual metathesis catalyst with an agent selected from the group consisting of (i) a salt and/or an ester of a phosphorous oxo acid, (ii) a derivative of the phosphorous oxo acid in which at least one P—H bond has been replaced by a P—C bond, (iii) a salt and/or an ester of the derivative, and (iv) combinations thereof; (d) separating the olefins in the metathesized product from the esters in the metathesized product; and (e) transesterifying the esters in the presence of an alcohol to form a transesterified product and/or hydrogenating the olefins to form a fully or partially saturated hydrogenated product.
