When it was used for gas-liquid-solid three-phase methanol synthesis

an impinging stream reactor showed good heat and mass transfer performance.In the impinging stream reactor

the catalyst slurry was atomized into droplets of several micrometers in size which provided a huge interface between gas and slurry phase.The effects of temperature

pressure

gas flow rate

slurry recirculation flow rate and number of nozzles on methanol productivity were investigated.The results showed that a pressure increase from 3.8 MPa to 5 MPa doubled methanol productivity

and at a gas flow rate up to 22.4 L·min-1

methanol productivity kept constant.The increases in slurry recirculation flow rate and in the number of multi-nozzle also resulted in the increase of methanol productivity.When space velocity was low

the impinging stream reactor had the same methanol productivity as compared with other reactors such as fixed bed reactor

agitated reactor and slurry bubble column.However

at a high space velocity the impinging stream reactor had higher methanol productivity than those of other reactors.
