Abstract

The invention discloses a device for producing low-carbon olefin from an oxygen-containing compound in the technical field of petrochemical industry. The device is suitable for the characteristics of rapid reaction, strong heat release, relatively low catalyst-alcohol ratio, high product selectivity and the like of a process for preparing low-carbon olefin from a oxygen-containing compound, so that the problem of relatively low selectivity of the low-carbon olefin in the prior art is solved, the advantages of the reaction can be brought into play to the greatest extent, and the selectivity of the low-carbon olefin is improved.

Description

technical field [0001] The invention belongs to the technical field of olefin preparation, in particular to a device for producing low-carbon olefins from oxygen-containing compounds. Background technique [0002] Light olefins (ethylene, propylene, butadiene) and light aromatics (benzene, toluene, xylene) are the basic raw materials for petrochemicals. The traditional production route of ethylene and propylene is through the cracking of naphtha, which has the disadvantage of being overly dependent on petroleum. Methanol-to-Olefin (MTO for short) is another process route for producing olefins such as ethylene and propylene from methanol. At present, the development of process technology has become mature. The industrialization of MTO technology has opened up a new process route for the production of petrochemical basic raw materials by gasification of coal or natural gas, which is conducive to changing the traditional coal chemical product structure and is an effective way ...
