Hydrodynamics and Mass Transfer Characteristics for Extractive Desulfurization of Diesel Using Highly Viscous Ionic Liquids in Microchannels: The Effect of the Phase Ratio and Temperature

Microreactor technology shows great potential in the enhancement of liquid–liquid mass transfer, which is important especially when highly viscous fluids are involved. This provides an attractive way to intensify extractive desulfurization (EDS) using ionic liquids (ILs) as effective technique for ultralow-sulfur diesel production. work concerns extraction dibenzothiophene model by [BMIM]PF6 a microchannel. The effects phase ratio and temperature on hydrodynamics transfer characteristics were investigated systematically. Higher beneficial forming stable slug flow droplet flow, well increasing overall coefficient. contributions during moving stages also discussed. Considerable contribution (9–64% whole) was found stage, coefficient stage can be predicted two-film model.
