Abstract
H2O2 decomposition in the propylene epoxidation system in a fixed-bed reactor was studied herein for the first time. The decomposition rate of H2O2 increased with increasing reaction temperature. The decomposition reaction followed the first-order kinetics equation at 30–50°C, whereas it did not follow the equation any longer at higher than 50°C. A kinetics equation for the H2O2 decomposition catalyzed by TS-1/SiO2 at 30–50°C was obtained, and the reaction activation energy Ea was calculated as 69.26 kJ/mol.
