Latest Patents

Johnson's latest patents include a method for the separation of sterols from low-acid feeds using magnesium silicate. This process involves an adsorptive separation technique that selectively adsorbs sterols from a feed mixture, such as tan oil or wool fat, while excluding other components. The high purity sterols are then recovered by desorbing the adsorbed sterols with methyl-t-butyl ether (MtBE), which has proven to be superior to previously used aromatic liquids like toluene and chlorobenzene. Another significant patent focuses on the purification of alpha naphthol-containing feedstock through an adsorptive separation process utilizing zeolite materials and a desorbent comprising a primary alcohol or an alkyl ester.
