Latest Patents

One of his latest patents focuses on the recovery of catalyst from coal liquefaction residues. This innovative process involves reducing the carbonaceous content of heavy bottoms produced during coal liquefaction. By contacting these residues with an aqueous solution of a mineral acid, along with an added alcohol and oxidizing agent, metal constituents can be extracted for reuse. Molybdenum is highlighted as a preferred metal constituent, with sulfuric acid, hydrochloric acid, or phosphoric acid serving as the mineral acids. The process also includes a solvent extraction step at elevated temperatures and pressures to enhance the recovery of valuable materials.

Another significant patent by Nadkarni addresses the beneficiation of coal and oil shale. This process utilizes electromagnetic radiation to solubilize mineral matter in carbonaceous solids when combined with an aqueous acid solution. The application of electromagnetic energy allows for the treatment of these materials at lower temperatures and pressures, resulting in beneficiated solids with reduced inorganic constituents.
