FIELD: technological processes.
SUBSTANCE: invention relates to a method of producing light olefins, where in a method of producing light olefins by continuous contact of feedstock based on oxygen-containing compounds and a catalyst for carrying out the dehydration reaction, the reaction pressure P of dehydration reaction is in range 1.2–2.8 MPa, hourly space velocity of feed of H in the dehydration reaction is in range of 7–250 h-1, where in the dehydration reaction, H and P satisfy a mathematical function H=f(P), which is a strictly increasing function.
EFFECT: method of producing light olefins is realized in a simple and continuous production process, leads to a significant increase in the production of light olefins and is characterized by high safety.
