摘要： The present application discloses a coke control reactor, a device for preparing low-carbon olefins from an oxygen-containing compound, and a use thereof. The coke control reactor includes a riser reactor and a bed reactor; the bed reactor includes a bed reactor shell, and the bed reactor shell encloses a reaction zone I, a transition zone, and a gas-solid separation zone I from bottom to top; a bed reactor distributor is arranged in the reaction zone I; a coke controlled catalyst delivery pipe is arranged outside the reaction zone I; an upper section of the riser reactor penetrates through a bottom of the bed reactor and is axially inserted in the bed reactor; and an outlet end of the riser reactor is located in the transition zone. The coke control reactor can control the conversion and generation of coke species in a catalyst. On the one hand, inactive large-molecule coke species remaining in a regenerated catalyst are converted into small-molecule coke species; and on the other hand, a riser reactor raw material and a bed reactor raw material can also enter the catalyst to generate highly-active small-molecule coke species to improve the selectivity for ethylene.

摘要： Disclosed are a catalyst pre-hydrocarbon-pooling method and a pre-hydrocarbon-pooling device, relating to the technical field of preparation of low carbon olefins. A regenerated catalyst enters a pre-hydrocarbon-pooling reactor, and a pre-hydrocarbon-pooling reaction occurs between the regenerated catalyst and an activation medium to form "hydrocarbon pool" active species. "Pre-hydrocarbon-pooling" treatment is performed on the regenerated catalyst by providing a pre-hydrocarbon-pooling device, so that the regenerated catalyst forms the "hydrocarbon pooled" active species and carbon deposition before entering into an oxygenate conversion reactor, by way of which "hydrocarbon pool" active species distribution and coke distribution of the catalyst in the conversion reactor are improved. This shortens or eliminates a reaction "induction period" and improves the catalytic activity and selectivity of the regenerated catalyst for a reaction of an oxygenate to low-carbon olefins.

摘要： Methods for treating or rejuvenating a spent catalyst are disclosed. Such methods can employ a step of halogenating the spent catalyst, followed by decoking the halogenated spent catalyst. The halogenation step can utilize fluorine and chlorine together, or fluorine and chlorine can be applied sequentially.

摘要： A process is disclosed for an improved catalyst regeneration process to improve catalyst stability and hence increase overall catalyst life. The process includes passing a spent catalyst stream to a first, or upper, combustion zone to partially regenerate the catalyst through controlled combustion of the carbon on the catalyst. The first combustion zone will burn off a high fraction of hydrogen at lower temperatures generating a large fraction of H
2 O. The partially regenerated catalyst is passed to a second, or lower, combustion zone to burn off the remaining coke at the needed high severity operation. The second combustion zone will burn off the remaining coke at a higher temperature and higher oxygen gas inlet concentration.
