Title: Inventor Profile: Lawrence J. Karas
Introduction
Lawrence J. Karas is a notable inventor based in West Chester, PA, known for his significant contributions to the field of fuel purification technologies. Throughout his career, he has been awarded a total of 16 patents, reflecting his innovative approach to solving complex challenges in fuel chemistry.
Latest Patents
Among his latest inventions are two noteworthy patents:
1. **Desulfurization Process** - This invention describes a method of purifying fuels containing organosulfur impurities. The process involves oxidizing the fuel with an organic hydroperoxide in the presence of an oxidation catalyst to form a sulfone product. This product is then extracted via solid-liquid or liquid-liquid extraction. Finally, the fuel is treated with a decomposition catalyst to remove any remaining organic hydroperoxide.
2. **Organosulfur Oxidation Process** - In this patent, Karas outlines a method for purifying fuel streams containing both organonitrogen and organosulfur impurities. The first step involves treating the fuel stream to extract organonitrogen impurities, thereby reducing the nitrogen content by at least 50 percent. Following the separation and recovery of the nitrogen-depleted fuel, the organosulfur impurities are oxidized with an organic hydroperoxide in the presence of a titanium-containing silicon oxide catalyst. This results in sulfones that can be more easily removed from the fuel stream compared to their non-oxidized counterparts.
Career Highlights
Lawrence J. Karas has a remarkable professional background, having worked with respected companies in the chemical industry, including Arco Chemical Technology and Lyondell Chemical Technology. His experience in these organizations has significantly contributed to his expertise and insights in fuel technology innovations.
