Industrial HPPO process suffers from the use of CH 3 OH solvent, leading to energy‐intensive and lengthy purification operations. Herein, by using a microspheric TS‐1 catalyst and a fluidized bed reactor, we realized a solvent‐free gas‐phase epoxidation of propylene, in which, 18% C 3 H 6 conversion and 97% PO selectivity have been achieved with 73% H 2 O 2 utilization. Furthermore, the gas‐phase epoxidation proceeds with an excellent stability, attributed to use of the fluidized bed reactor.
