Title: Innovations of Xunzhi Zhao in Hydrocarbon Separation
Introduction
Xunzhi Zhao is a notable inventor based in Tianjin, China. He has made significant contributions to the field of chemical engineering, particularly in the area of hydrocarbon separation. His innovative methods have the potential to enhance the efficiency of diesel oil purification processes.
Latest Patents
Xunzhi Zhao holds a patent for a "Method for simulated moving bed to adsorb and separate polycyclic aromatic hydrocarbons." This method utilizes zeolite, metal oxide, and metal-modified materials as adsorbents. The process begins with diesel oil flowing through a pre-treatment adsorbent to eliminate trace impurities. Subsequently, the purified diesel oil passes through a simulated moving bed, allowing for the separation of polycyclic aromatic hydrocarbons (PAHs) from the diesel oil. The periodic switching of valves facilitates the relative movement of adsorption beds, while a desorbent is pumped in to wash out the PAHs, achieving continuous adsorption-regeneration operation. Simple distillation is then employed to separate the desorbent from the clean diesel oil and PAHs, resulting in the recovery of both fractions. Remarkably, the PAHs removal rate can reach up to 90%, and the separated desorbent can be recycled.
Career Highlights
Xunzhi Zhao has worked with prominent organizations such as Cnooc Tianjin Chemical Research & Design Institute Co. Ltd. and China National Offshore Oil Corporation. His experience in these companies has contributed to his expertise in chemical processes and innovations.
