Solid effects on gas-liquid mass transfer in catalytic slurry system of isobutene hydration over fine ion exchange resin particles

摘要

To study solid effects on gas-liquid mass transfer in slurry system accompanied by chemical reaction,the experiments of isobutene hydration over fine cation exchanger resin were performed in three-phase slurry catalytic reactor.The mathematical model for the reactor with multi-parameter estimation procedures was developed to obtain the volumetric liquid-side mass transfer coefficient (k_La).The experimental study with different catalyst particle sizes and catalyst solid loadings has shown that gas-liquid mass transfer can be significantly enhanced by chemical reaction on the surface of fine catalyst particles in the liquid film at low solid concentrations.The k_La increases with decreasing catalyst particles mean size,and with increasing catalyst loading.
