  • Catalytic process for the preparation of light olefins from methanol in fluidized bed reactor
    Patent number: 6710218
    Abstract: Methanol is converted in light molecular olefins C2-C4 with 93-100% degree of transformation and more than 90% selectivity in which more than 80% are ethylene and propylene upon a microspherical catalyst based on SAPO-34 zeolite, with continuous reaction-regeneration in a fluidized bed reactor-regenerator system. Ethylene/propylene ratio is changed in relatively large limits 0.69-1.36, by the modification of reaction temperature and space velocity of the feed.
