Experimental investigations have been carried out to study the performance of
trickle bed reactor. The effect of key parameters that play predominate role in the
performance of trickle bed reactor was studied. A laboratory unit was constructed
for this purpose where a versatile reactor setup required " high pressure stainless
steel reactor of 0.05m i.d × 1.25m height", in which the hydrodynamic
experiments carried out under different operating condition namely, superficial gas
velocity and liquid velocity , reactor pressure, bed temperature .Air–water system
was used for hydrodynamic experiments pressure drop, dynamic liquid holdup, and
axial dispersion coefficients were estimated. The results also show that the
dynamic liquid holdup increases with increasing liquid velocity and decreases
with increasing superficial gas velocity and bed temperature. Axial dispersion
tends to increase with increasing superficial gas and liquid velocities while it
decreases with increasing bed temperature.
