Title: **Siqing Zhong: A Pioneer in Gas Replacement and Hydrogenation Processes**
Introduction
Siqing Zhong, an accomplished inventor based in Shanghai, China, has made significant contributions to the fields of gas replacement processes and chemical engineering. With a total of 15 patents to his name, he continues to innovate and push the boundaries of technology, particularly in the area of nitro compound hydrogenation reactions.
Latest Patents
Zhong's most recent patents include a gas replacement process and apparatus specifically designed for nitro compound hydrogenation reaction processes. The patented gas replacement process involves two critical steps: initially exposing a stream to gas replacement in the presence of a first replacement gas, followed by exposure to a second replacement gas. A unique aspect of this process is the requirement that the ratio of the superficial velocities of the two gases, denoted as V2/V1, must be equal to or greater than 1.5. In addition, Zhong has developed a fluidized apparatus containing a double-trapezoid structural member, which is instrumental in optimizing the nitro compound hydrogenation reaction. This apparatus includes a shell, a gas distributor, and an inner chamber defined by the inner wall of the shell and the upper surface of the gas distributor. A perforated plate, strategically positioned in this chamber, has a specific opening rate ratio defined as A1/A2, ranging from 0 to 0.95.
