Title: Innovations by Charles Woo in Hydrocarbon Lubricating Oils
Introduction
Charles Woo is an accomplished inventor based in Sarnia, Canada. He has made significant contributions to the field of hydrocarbon lubricating oils, holding a total of 2 patents. His work focuses on the synthesis of lubricants that are particularly useful in extreme conditions.
Latest Patents
One of Woo's latest patents involves the synthesis of low viscosity low pour point hydrocarbon lubricating oils. This innovation allows for the production of synthetic hydrocarbon lubricating oils with very low pour points and low viscosities. The process involves polymerizing alpha-olefins with carbon chains ranging from 5 to 20, preferably between 10 to 14 carbon atoms. This is done at temperatures between 300°F to 800°F in the presence of an acidic catalyst, specifically a crystalline aluminosilicate zeolite molecular sieve-type. The resulting products are predominantly paraffinic and naphthenic hydrocarbons, making them ideal for use as lubricants in arctic climates and other applications requiring low pour points, such as transformer oils.
Another notable patent by Woo focuses on aromatic oils produced through the thermal polymerization of refinery streams. This process upgrades a heat-soaked polymer by-product from gasoline production. The method involves thermal polymerization followed by hydrotreating or hydrogenation. The hydrotreatment is conducted under mild conditions to preserve the aromatic ring structure, while hydrogenation is performed under more severe conditions to modify the aromatic rings. The products from this process can be utilized as aromatic oils of light color or as naphthenic oils, depending on the severity of the hydrogenation.
