START-UP METHOD FOR REACTION-REGENERATION UNIT USED TO PREPARE LIGHT OLEFINS FROM METHANOL |
摘要 |
The invention provides a start-up method for a reaction-regeneration unit for preparing light olefins from methanol, which comprises: (a) heating a regenerator with an auxiliary combustion chamber and a reactor with a start-up furnace; (b) charging a catalyst into the regenerator and reactor; (c) closing a spent catalyst slide valve and a regenerated catalyst slide valve after the reactor reaches about 350° C. or more; (d) feeding methanol to the reactor after the dense phase stage of the regenerator reaches about 350° C. or more; (e) opening the spent catalyst slide valve and introducing a carbon deposited catalyst from the reactor to the regenerator after the dense phase stage reaches about 400° C. or more and the average amount of carbon deposits on the catalyst in the reactor reaches about 2.5% or more; (f) raising the regenerator to above about 580° C.; and (g) stopping the start-up furnace and auxiliary combustion chamber.
