MASS-TRANSFER CHARACTERISTICS OF A PILOT PULSED BAFFLED REACTOR

We report experimental measurements on the air-water mass transfer cha racteristics of a pilot pulsed baffled reactor. The experiments have i dentified, for the first time, the optimal baffle spacing and the opti mal superficial gas velocity for mass transfer in the reactor. The mas s transfer characteristics were also examined under various operationa l conditions and were corrected for the effect of temperature and oxyg en probe response. The experimental results indicate that the mass tra nsfer rate depends strongly on the combination of the baffle spacing, oscillation frequency and amplitude. The mass transfer data are also c orrelated in terms of power density and superficial gas velocity, and compared with those from a stirred tank reactor.
