Abstract: The invention provides a process for removing fatty acid metal soaps derived from metals with an atomic number from 27 to 29 from hydrogenated fatty products comprising separating solid metal precipitated under the influence of hydrogen at a pressure ranging between 0.05 and 10 MPa from the hydrogenated fatty products. Preferably the hydrogen pressure is between 0.2 and 5 MPa. Preferably the metal is nickel. It is recommended to effect the separation by filtration, using a filter comprising vertical pressure leaves. Also it is possible to treat the hydrogenated fatty product with hydrogen under a pressure between 0.05 and 10 MPa before separating the metal from the fatty product.
