English Abstract

The research in this thesis presents two part of work hydrodynamics and kinetics.

The hydrodynamics in atrickle bed reactor(TBR) in non-ambient conditions are studied for Air–water system was used, pressure drop, dynamic liquid holdup, and axial dispersion coefficients were estimated.

It has been demonstrated from the experimental results that the pressure drop tends to increase with increasing superficial gas and liquid velocity and reactor pressure while it tends to decrease with increasing bed temperature.

The results also show that the dynamic liquid holdup increases with increasing liquid velocity and decreases with increasing superficial gas velocity and bed temperature.

For higher superficial gas and liquid velocities the increasing in axial dispersion is observed while it decreases when increasing bed temperature.

Catalytic wet oxidation of phenol was studied in the present work.

The effect of LHSV, superficial gas velocity, reactor pressure, temperature and initial phenol concentration was studied for conventional operation and saturation condition.

Result show that phenol conversion increased with increasing reaction temperature, reactor pressure, and superficial gas velocity of oxygen, while decreased with increasing liquid hourly space velocity (LHSV).

The initial phenol concentration had little effect on the conversion.

The results exhibit that the highest phenol conversionwas obtained (saturation condition).
