dc.description.abstract A novel method to simultaneously measure liquid-solid-mass-transfer and external wetting efficiency was employed at column to particle ratios of 10, 6 and 3. Two prewetting procedures representing the upper (Kan) and lower (Levec) hysteresis branches were used. For a multipoint distributor on a Kan-prewetted bed wetting efficiency and the specific masstransfer coefficient were almost unaffected by column diameter. The multipoint distributor on a Levec-prewetted bed exhibited a decrease in specific mass transfer with decreasing column diameter. Pointsource experiments resulted in significantly lower wetting and mass-transfer measurements with an increasing trend with respect to decreasing column diameter. The results indicate that with proper distribution and prewetting, the effect of column diameter on averaged wetting and liquid-solid mass transfer is almost negligible, a powerful result considering the importance of these parameters on reaction experiments. en_US
