Title: Yujing Chen and the Development of ZSM-23 Zeolite

Introduction

Yujing Chen is an inventor associated with Dalian, China, and has worked with China Petroleum & Chemical Corporation and Sinopec Dalian Research Institute of Petroleum and Petrochemicals. His listed patent focuses on ZSM-23 zeolite, a material designed to combine a rich mesoporous structure with strong hydrothermal stability.

Latest Patents

Chen is associated with 1 patent: “ZSM-23 Zeolite and Preparation Process and Use Thereof.” The invention describes a zeolite in which mesopores measuring 3–8 nanometers account for 45–90% of the material’s total pore volume. It also specifies relative crystallinity of 95–120% and retention of 95–100% after two hours of steam treatment at 600°C.

The preparation process involves selecting or preparing a silicon source, such as amorphous silica, treating that source with alkali, and then using the treated silica to prepare the ZSM-23 zeolite. The resulting material is described as having both a substantial mesoporous structure and good resistance to hydrothermal treatment.

Career Highlights
