Gas Phase Epoxidation of Propylene with TS-1 and in ... - ScienceDirect
Gas phase epoxidation of propylene was performed by directly contacting propylene and gaseous H 2 O 2 on the surface of TS-1 catalyst in an integrated reactor. The gaseous H 2 O 2 was produced in situ by a H 2 /O 2 plasma. The H 2 O 2 formation rate can be enhanced by increasing the power density of the H 2 /O 2 plasma reactor. The yield and selectivity for propylene oxide (PO) can be ...
