چکیده

A fluidized bed reactor with ultraviolet lamp and TiO2/silica photo-catalyst prepared in our laboratory was used as a photo-reactor to degrade toluene in a simulated toluene-air mixture. The effects of operating parameters including initial toluene concentration, superficial gas velocity, ultraviolet light intensity and catalyst bed height on degradation rate of toluene have been investigated in this paper. The experimental results showed that degradation rate of toluene was independent of initial toluene concentration in the tested range of 20-55 mg/m, but decreased with increasing the inlet toluene concentration. The degradation rate of toluene increased with increasing gas velocity at gas velocities below 4.0 cm/s, but decreased with increasing gas velocity at gas velocities higher than 4.0 cm/s. The results also showed that the degradation rate of toluene increased with increasing UV light intensity and catalyst bed height.

The 12th International Conference on Fluidization - New Horizons in Fluidization Engineering

An experimental approach is proposed to investigate the gas-solid structure in the vicinity of a sparger nozzle in a fluidized bed. The local hydrodynamics were studied under injection velocities ranging between 0 and 100 m/s and three orientations. A fiber-optic probe was used to measure the instantaneous local particle holdup near the tip of the sparger nozzle. Under the investigated conditio...

Fluidization of Initialty Segregased Equidensity Binary System

Fluidization of initially segregated binary mixtures has been investigated for particle systems of the same material. This paper reports experiments conducted in 0.055m diameter fluidizes bed for binary mixtures composed of sands whose sizes ranged from 450 to 1450mm. An empirical relationship, Utf = 0.95 UF (dR)0.87, was derived in terms of the minimum fluidization of the smaller particle, UF ...
