AI Technical Summary
Technical Problem
Existing gas-liquid reactors have a small gas-liquid interface, resulting in poor mixing, long reaction times, and difficulty in recovering and utilizing homogeneous catalysts, which affects reaction efficiency and cost.
Method used
A shell-and-tube microbubble gas-liquid reactor is adopted. By setting a through tube inside the shell and setting holes on the tube wall to allow limited gas feed to pass through, the gas-liquid contact interface is increased, and the catalyst can be recycled online by combining it with a membrane separator.
Benefits of technology
It significantly increases the gas-liquid contact interface, improves mixing effect, shortens reaction time, increases reaction efficiency, and enables catalyst recycling, thereby reducing costs.
