Title: Innovator Robert L. Chiang: Pioneering Advances in Zeolite Technology
Introduction
Robert L. Chiang, an esteemed inventor based in Anaheim, California, has made significant contributions to the field of zeolite technology, holding a total of six patents. His work has focused on improving the silica/alumina ratio in zeolites, leading to advancements that can be utilized in various industrial applications.
Latest Patents
Chiang's recent patents include a groundbreaking innovation for producing a sodium Y type faujasite with a high silica/alumina ratio. This process involves lowering the active soda content in the synthesis slurry by incorporating an acid or an aluminum salt solution, such as aluminum sulfate, into the sodium silicate mixture. This method allows for a more efficient use of starting materials, resulting in Y zeolites with a silica/alumina ratio of 5.0 and higher. These zeolites exhibit a remarkable level of crystallinity and an absence of occluded silica, making them more thermally stable and effective as catalysts in petroleum fraction treatments.
Additionally, Chiang has developed a method for the manufacture of catalytically active silica-alumina and silica-alumina-rare earth oxide cogels. This involves the reaction of aluminate and silicate solutions to create a pregel, which is then mixed with acidic rare earth and/or aluminum salt solutions, showcasing his innovative approach in catalysis.
