Fluidized reaction method for synthesizing propylene oxide by gas phase epoxidation of propylene and hydrogen peroxide |
| abstract |
A fluidized reaction method for synthesizing propylene oxide by gas phase epoxidation of propylene and hydrogen peroxide relates to a microspherical alkali metal ion modified titanium silicalite zeolite TS-1 catalyst applicable to the reaction method, and a preparation method thereof. A gas-solid phase fluidized epoxidation method refers to a gas phase epoxidation method in which the raw materials of propylene and hydrogen peroxide are directly mixed in the gas phase under normal pressure and temperature above 100°C and the feed gas enables the titanium silicalite zeolite TS-1 catalyst to be fluidized in an epoxidation reactor. A catalyst applicable to the reaction method is a microspherical alkali metal ion modified titanium silicalite zeolite TS-1 catalyst which has the main characteristic that alkali metal cations are reserved on the titanium silicalite zeolite. The method of the present invention is beneficial to inhibit the self-decomposition side-reaction of hydrogen peroxide, beneficial to disperse the reaction heat and rapidly withdraw the heat, beneficial to improve the utilization rate of the catalyst and increase the productivity of the catalyst, and beneficial to industrial application and industrial production safety. |
