1微化工科学和技术的起源化学工业发展的一个重要趋势就是安全、高效、节能,这一目标有望通过微化工技术将设备小型化、模块化和化工过程集成化得以实现[1—3]。微化工技术是现代新型化工技术,也是重要的过程强化技术,研究对象为时空特征尺度在数微米到数百微米间的微化工系统。由于特征尺度小,微反应器内流体接触面积大、扩散距离短,具有极高的传质传热速率,能有效提高过程的效率,因而特别适用于快速、强放
1 The origin of micro-chemical science and technology An important trend in the development of chemical industry is safety, high efficiency and energy-saving. This goal is expected to be achieved through micro-chemical technology to miniaturize equipment, modularization and chemical process integration [1-3]. Micro-chemical technology is a new modern chemical technology, but also an important process enhancement technology, the object of study for the micro-chemical systems in the space-time feature scale of several microns to hundreds of microns. Due to the small characteristic scale, the contact area of the fluid in the microreactor is large, the diffusion distance is short, and the mass transfer rate is very high, which can effectively improve the process efficiency. Therefore, the microreactor is especially suitable for rapid and strong
