Title: Innovator Chang Shu: Pioneering Methods for Environmental Purification

Introduction

Chang Shu, an inventive thinker based in Tianjin, China, has made a significant impact in the field of chemical engineering. His innovation focus lies in developing effective methods for the removal of harmful compounds from diesel oil, particularly polycyclic aromatic hydrocarbons (PAHs). With a patented method designed to enhance environmental purification, Shu showcases the essential role of inventors in addressing modern environmental challenges.

Latest Patents

Chang Shu holds a notable patent for a "Method for simulated moving bed to adsorb and separate polycyclic aromatic hydrocarbons." This innovative approach employs zeolite, metal oxides, and metal-modified materials as adsorbents. The process begins with diesel oil passing through a pre-treatment adsorbent to eliminate trace impurities, followed by flowing through a simulated moving bed for effective PAH separation. Periodic switching of valves facilitates the relative movement of adsorption beds, while a desorbent is utilized to wash out PAHs, allowing for continuous adsorption-regeneration operations. Simple distillation is then applied to separate desorbent from clean diesel oil and PAHs, achieving an impressive PAH removal rate of up to 90%. The separated desorbent can also be recycled, emphasizing the method's environmental sustainability.

Career Highlights

Chang Shu has collaborated with prominent organizations during his career. He has worked at the CNOOC Tianjin Chemical Research & Design Institute Co. Ltd. and the China National Offshore Oil Corporation. His roles at these companies have undoubtedly contributed to his expertise and ground-breaking innovations in the field.
