Title: The Innovative Contributions of Tomoya Ishikawa
Introduction
Tomoya Ishikawa is a prominent inventor based in Yamaguchi, Japan. He has made significant contributions to the field of zeolite production, holding a total of 5 patents. His work focuses on methods that enhance the efficiency and applicability of zeolites in various industrial processes.
Latest Patents
One of Ishikawa's latest patents is a method for producing AEI zeolite. This innovative production method allows for the creation of AEI zeolite with a silica-to-alumina molar ratio that is suitable for use as a nitrogen oxide-reducing catalyst. The method is notable for its shorter crystallization time and higher yield compared to traditional methods that do not utilize crystalline aluminosilicate as a starting material. The process involves hydrothermally processing an amorphous composition and crystallizing it with an organic structure-directing agent.
Another significant patent is for a CHA-type zeolite, characterized by a molar ratio of silica to alumina of less than 13 and sodium content between 100 ppm and 2000 ppm. This CHA-type zeolite is produced through a method that includes crystallizing a composition with a specific structure-directing agent and then treating the crystallized product to remove the agent while ensuring the desired sodium and potassium ratios.
