Abstract
A method of preparing epoxypropane by direct epoxidation of propylene includes the steps of contacting a mixed gas consisting of a reaction feed gas and a diluent gas with a catalyst to carry out reaction under reaction conditions of propylene epoxidation to prepare epoxypropane. The reaction feed gas contains propylene, oxygen gas and hydrogen gas while at least a portion of the diluent gas is a gaseous olefin. Using gaseous olefin as at least a portion of the diluent gas to perform propylene epoxidation can significantly extend service life of the catalyst, effectively reduce the used amount of diluent gas, and improve the reaction selectivity and propylene conversion rate.
