Propylene oxide (PO) is one of the important propylene derivatives with high reactivity, which is used extensively as a raw material for the manufacture of numerous commercial chemicals. The titanosilicate-catalyzed hydrogen peroxide propylene oxide process (HPPO) is considered to be most advantageous because it is highly economical and ecofriendly, giving only H2O as the theoretical byproduct and achieving high PO selectivity under mild reaction conditions. The industrial HPPO process is generally carried out in a fixed-bed reactor using the shaped titanosilicate catalysts.
