✦ Synopsis

Ahstraet-The behavior of a trickle bed in which the catalytic packing was incompletely wetted was investigated using the selective hydrogenation of crotonaldehyde to n-butyraldehyde as a model reaction. The reaction was carried out at near ambient conditions using palladium deposited on porous ahunina pellets as the catalyst. It was found that even when the extent of wetting was large, reaction taking place on the dry parts of the catalyst largely dominated the overall reaction rate.

## Abstract The wet air oxidation of phenol over a commercial active carbon catalyst was studied in a trickle bed reactor (TBR) in the temperature and oxygen partial pressure ranges of 120–160 °C and 0.1–0.2 MPa, respectively. The performance of the active carbon was compared in terms of phenol and
