【Abstract】 Liquid-solid contacting efficiency of the catalyst of ion-exchange resin in the catalyst capsule is measured by the tracer method. It is indicated that liquid-solid contacting efficiency is affected more by liquid flow rate than gas flow rate, which increases with liquid flow rate. When the liquid flow rate is greater than 1.9 ×10 -3 ?m 3/(m 2·s), it tends towards 1, but increases slightly with the increase of gas flow rate.更多还原
