Styrene Biofiltration in a Trickle-Bed Reactor

The biological treatment of styrene waste gas in a trickle–bed filter (TBF) was investigated. The bioreactor consisted of a two-part glass cylinder (ID 150 mm) filled with 25 mm polypropylene Pall rings serving as packing material. The bed height was 1m. Although the laboratory temperature was maintained at 22 °C, the water temperature in the trickle–bed filter was slightly lower (about 18 °C)....

Experimental Analysis and Evaluation of the Mass Transfer Process in a Trickle-bed Reactor

A transient experimental analysis of a three-phase descendent-cocurrent trickle-bed H2O/CH4Ar/γ-Al2O3 system was made using the stimulus-response technique, with the gas phase as a reference. Methane was used as a tracer and injected into the argon feed and the concentration vs time profiles were obtained at the entrance and exit of the bed, which were maintained at 298K and 1.013 10 Pa. A math...

Analysis of Foaming Flow Instabilities for Dynamic Liquid Saturation in Trickle Bed Reactor

The effects of different parameters on the hydrodynamics of trickle bed reactors were discussed for Newtonian and non-Newtonian foaming systems. The varying parameters are varying liquid velocities, gas flow velocities and surface tension. The range for gas velocity is particularly large, thanks to the use of dense gas to simulate very high pressure conditions. This data bank has been used to c...

I Methanol Synthesis in a Trickle Bed Reactor

INTRODUCTION The conversion of synthesis gas to methanol is practiced commercially in gas phase fixed bed reactors over a Cu/Zn/Al,O1 catalyst. However, because of the highly exothermic nature of the synthesis reactions, heat dissipation has been a bottleneck in the reactor design and process configuration. Moreover, coalderived synthesis gas, having a low H,/CO ratio, is not suitable for use i...
