Direct O-2 epoxidation of propylene by the membrane reactor loaded with Ag-Sr catalyst
A novel membrane reactor process using porous alpha-Al2O3 tube loaded with silver-strontium catalyst realized direct O-2 epoxidation of propylene with notable selectivity of propylene oxide. Segregated feed of propylene and O-2 combined with facile permeation of reactants and products across the membrane was essentially important for the membrane epoxidation process.
