Microchemicals: From "Bigger is better" to "small and efficient"

3. Technical difficulties remain

Chen Guangwen said that although the development of microchemical technology has been very rapid in the past decade, it is also necessary to be sobering to realize that although for some reaction processes, microreactors are the preferred device, there are still some reactions that are not suitable for microchemical systems. As a new field, there are still many problems that need to be further studied, such as structure optimization design and advanced manufacturing technology of micro-reaction system, system automatic control technology, anti-corrosion and anti-clogging technology of micro-reactor, industrial application and so on. "The application of microreactors is conditional, which is closely related to the principle of chemical reaction, as well as the control of reaction conditions such as temperature and flow rate, not as long as the use of microreactors can improve production efficiency, better selectivity, reduce 'three wastes', and no safety problems." The horseman stressed.

"This requires in-depth and substantive cooperation among relevant enterprises to carry out long-term industrial application demonstration operations for different types of chemical processes or reaction types, accumulate experience, and provide theoretical basis for the design, scale-up and operation of microchemical technology." Chen Guangwen said that during the "13th Five-Year Plan" period, in order to strengthen the strength to overcome the difficulties of micro-reaction technology, relevant enterprises need to vigorously strengthen the basic and applied basic research of micro-chemical engineering and technology, and solve the key common scientific problems in the field of micro-chemical engineering and technology. At the national level, more efforts should be made to recommend and promote micro-reaction technology and other advanced chemical technology that can achieve chemical process strengthening, process safety and energy saving and emission reduction.
