## Abstract The kinetics of aqueous phase catalytic hydrogenation of maleic acid to succinic acid were studied in a slurry reactor between 323 and 353 K using a hydrogen partial pressure range of 1.03–2.06 MPa, with a 5% Ru/Al~2~O~3~ catalyst. The initial rate data were analyzed using a power law m
Ru-, Rh-, and Pd/WO 3 -ZrO 2 catalysts were studied for the direct oxidation of ethylene to acetic acid. The catalytic activity and selectivity depended strongly on the noble metals used. Rh/WO 3 -ZrO 2 gave the highest conversion of ethylene, whereas Ru/WO 3 -ZrO 2 was almost inactive. The higher c
