Abstract
Disclosed is a process for producing light olefins, the process comprising: continuously contacting an oxygen-containing compound raw material with catalyst to have a dehydration reaction so as to prepare low-carbon alkene, the reaction pressure P of the dehydration reaction being 1-2 MPa, and the weight hourly space velocity H of the dehydration reaction being 15-50 h. The process of preparing light olefins has a simple and continuous operation process, reduces investment, greatly increases production of light olefins and has a high safety.
