1. utilize a method for the gaseous mixture regenerated methanol alkene catalyst of carbon dioxide and oxygen, concrete steps are as follows:

  • (1) by the Catalyst packing of inactivation in methanol-to-olefins process in reactor, in reactor, pass into carbon dioxide, purge 10 minutes;

    (2) temperature of reactor heating furnace is set, when the temperature in question response device rises to 200 DEG C from room temperature, carbon dioxide is switched to V (CO 2);

    V (O 2);

    V (CO)=(0%-80%);

    (10%-100%);

    the gaseous mixture based on carbon dioxide and oxygen of (0%-10%), start reaction of making charcoal, when temperature rises to 450 DEG C-800 DEG C, to make charcoal requirement according to difference, constant temperature 1-10 hour under regeneration temperature.
