| titleOfInvention | A method and device for improving the selectivity of oxygen-containing compounds to produce low-carbon olefins |
| abstract | The invention belongs to the technical field of low-carbon olefin preparation, and discloses a method for improving the selectivity of oxygen-containing compounds to low-carbon olefins. This is in contact with the activation medium, and a pre-hydrocarbon pool reaction occurs to form a "hydrocarbon pool" active species. After leaving the pre-hydrocarbon pool facility, the regenerated catalyst enters the conversion reactor for recycling. In the present invention, by setting up a pre-hydrocarbon pooling facility, the regenerated catalyst is subjected to "pre-hydrocarbon pooling" treatment, so that the regenerated catalyst forms "hydrocarbon pool" active species and carbon deposits before entering the reforming reactor, thereby improving the "hydrocarbon pooling" of the catalyst in the reforming reactor. Hydrocarbon pool "active species distribution and coke distribution, thereby shortening or eliminating the "induction period" of the conversion reaction, and improving the catalytic activity and selectivity of the regenerant oxygenate to light olefins reaction. |
