Title: **Innovative Contributions of Yusuke Naraki in Zeolite Technology**

Introduction

Yusuke Naraki, an accomplished inventor based in Yamaguchi, Japan, has made significant strides in the field of zeolite technology. With a total of eight patents to his name, Naraki's work focuses on enhancing the properties and manufacturing processes of CHA-type and β-zeolites. His contributions not only demonstrate his expertise but also represent advancements that could impact various industrial applications.

Latest Patents

Among Naraki's latest innovations is a CHA-type zeolite with a unique molar ratio of silica to alumina being less than 13, and a sodium content ranging from 100 ppm to 2000 ppm. This zeolite is manufactured through a specific method that involves crystallizing a carefully formulated composition. The inclusion of a structure-directing agent, specifically N,N,N-trialkylcyclohexylammonium cation, plays a crucial role in the crystallization process. The zeolite is further refined by removing the directing agent and exposing it to an ammonium-salt-containing solution.

Another key patent by Naraki is for a β-zeolite that boasts an SiO/Al ratio of less than 20, while maintaining or surpassing the heat resistance of conventional β-zeolites with a higher ratio. This innovative zeolite is distinguished by its specific characteristics observed through powder X-ray diffractometry, which measures the width of diffraction peaks. Furthermore, its production method involves a careful balance of ingredients including alkali sources and potassium, enhancing its properties significantly.
