The results of the research of hydrogenation reaction running in Trickle bed reactor (TBR) under condition of steady state or periodic pulse modulation of liquid feed are presented in the report. The effect od pulse period and split on reaction conversion including optimal operation conditions was determined. Yhe extensive hydrodynamic study of TBR was conducted and judged in terms of pressure drop profiles along the catalytic layer, liquid hold up and residence time distribution. Results of hydrodynamic study confirm determination of optimal operating conditions related to maximum conversion.

Transition events in trickle bed reactor under conditions of steady state and pulse regime has been studied experimentally in pilot plant trickle bed reactor at elevated pressures 2 and 5bar and temperatures 20 and 50oC. From hydrodynamic dependencies of pressure drops on gas and liquid velocities the transients lines between film and pulse regime have been determined. The effects of various variables flow rates, temperature, pressure, length of period and spilt have been verified with respect to pressure drop and pressure drop profile along trickle bed reactor operated in pulse regime.

The conductive method has been modified for hydrodynamic study in trickle bed reactor. Method for RTD measurements in liquid phase (steady state flow) has been developed and tested in glass laboratory scale TBR. The method for evaluation of experimental data was developed and RTD and liquid hold up calculated. The agreement between experiment and calculated results is good.
