Microchemical engineering is a promising leading discipline of modern chemical engineering, which focuses on the study of fluid flow, heat and mass thansport phenomena and reaction principles under Micro spatio-temporal scales. Compared with the conventional chemical equipment, microreactor predominance in its highly efficient heat and mass transfer,and inherent operating safety. Micro-reactor with modular structure design can be, easily scaled up and promote the rapid commercialization of laboratoryscale results. The development and application of microchemical system will intensify the traditional chemical process, and improve greatly the systems efficiency and reduce the plant size and energy consumption. Microreaction technology has emerged as one of the most advanded techniques in future chemical industry.
Current focus of interest includes:
1. Flow behavior, mass transport phenomena and reaction principles under micro spatio-temporal scales.
(1) Flow behavior of single phase.
(2) Flow behavior and mixing of miscible or immiscible two phases.
(3) Chemical engineering process principles within the microchemical devices.
2. Design, fabrication, and manufacturing of microdevice.
3. System optimization and process simulation of microchemical system.
4. R&D in applications of microchemical technology.
Liquid-liquid reaction, gas-liquid reaction, including sulfonation, nitration, amidation, diazotization, oxidation, fluoride, chloride and other highly exothermic reaction and rapid synthesis process of nano-materials.
5. Scale-up by numbering up concept and system integration of microchemical system. Biography
