Selective decomposition of hydrogen peroxide in the epoxidation effluent of the HPPO process

This work describes the selective H2O2 decomposition in the exit stream of the epoxidation reactor employed in the Hydrogen Peroxide-Propylene Oxide (HPPO) process. Pd/Al2O3 and Pt/Al2O3 catalysts were tested. The effects of the reaction temperature and the pH of the solution on catalyst performance...
