Solid-liquid mass transfer in a gas-liquid-solid three-phase reversed flowjet loop reactor

Solid-liquid mass transfer in gas-liquid-solid three-phase reversed flow je t loop reactors was experimentally investigated by means of an electrochemi cal method, and the effects of liquid jet flow rate, gas jet flow rate, par ticle size, particle density and nozzle diameter on the solid-liquid mass t ransfer coefficient were evaluated. The solid-liquid mass transfer coeffici ents in gas-liquid-solid three-phase reversed flow jet loop reactors are hi gher than those in the corresponding liquid-solid two-phase reversed flow j et loop reactors. A generalized correlation is developed which more accurat ely and conveniently predicts solid-liquid mass transfer in gas-liquid-soli d three-phase reversed flow jet loop reactors.
