Paper deals with study of behavior of trickle-bed reactor under periodic feed rate modulation conditions. Unsaturated hydrocarbons hydrogenation (typical for pyrolysis gasoline hydrotreatment) was investigated. As model reactions hydrogenation of cyclohexene and styrene on egg-shell type palladium catalyst was studied. Numerical solution of theoretical model predicting strong effect of period split on a reactor performance is discussed. Periodic operation can enhance trickle-bed productivity due to decrease of flowing liquid film thickness and by increase of mean reactor temperature. Brief data about experimental pilot plant unit for investigation of dynamic operation of trickle bed reactor are presented.

Catalytic hydrogenation of 40% aqueous solutions of D-glucose to D-glucitol was studied in a high-pressure trickle-bed reactor. The reactions were performed on a supported nickel catalyst at temperatures ranging from 115 to 165 °C and in the pressure range 0.5 to 10 MPa. The order of the reaction with respect to hydrogen is 0.65 and apparent activation energy 23.8-48.5 kJ mol-1, the latter depending on initial molar glucose concentration and density and viscosity of the solution. The influence of external diffusion is necessary to take into account for scaling-up the process.

Catalytic activity of CuO-supported catalyst in phenol oxidation, and the influence of reaction conditions, viz. temperature (125-170 °C), oxygen partial pressure (1-7 MPa) and liquid feed (30-760 ml h-1), in the continuous operation using 17.9 mm i.d. trickle-bed reactor is presented. The hydrodynamic impact on the three-phase trickle-bed reactor performance in an environmental application of catalytic wet oxidation was also investigated. The results of trickle-bed operation were strongly influenced by wetting efficiency. An insufficient catalyst wetting can be to compensated by filling the catalyst bed voids by fine glass spheres. In the case of the gas transfer limited reaction, a better wetting of the catalyst can lead to worse reactor performance due to lower reaction rates.
