1. Mutiphase transport in microscale channels

Focus on multiphase flow and mass transfer in microchannels, including gas-liquid, liquid-liquid and gas-liquid-liquid systems; Develop highly efficient micro-dispersion and transport models for better design of microreactors.

2. Microreactors based intensification and process innovation

 The mixing, extraction and reaction in microchannel reactors. Aiming to intensify the mass transfer between immisicble phases to improve reaction performance.

Develop efficient technology for CO₂ captrue, to realize methane purication from oilfield gas, biogas, landfill gas and FLNG, etc.

3. Ultrasonic intensification in microreactors

Use ultrasound cavitation to intensifiy transport (i.e., emulsion) and reaction in microreactors.
