Title: Innovations of Jiazhong Zang in Hydrocarbon Separation
Introduction
Jiazhong Zang is a notable inventor based in Tianjin, China. He has made significant contributions to the field of hydrocarbon separation through his innovative methods. His work focuses on improving the efficiency of separating polycyclic aromatic hydrocarbons (PAHs) from diesel oil.
Latest Patents
Jiazhong Zang holds a patent for a method for a 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 the simulated moving bed, allowing for the separation of PAHs. The periodic switching of valves facilitates the relative movement of adsorption beds, while desorbent is pumped in to wash out the PAHs, achieving continuous adsorption-regeneration operation. Simple distillation is then employed to separate the desorbent from clean diesel oil and PAHs, resulting in a PAHs removal rate of up to 90%. The separated desorbent can be recycled, enhancing the sustainability of the process.
Career Highlights
Jiazhong Zang 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 engineering and hydrocarbon processing.
