Title:
【発明の名称】流動床反応装置において低分子量オレフィンをメタノールから調製するための触媒的方法
Document Type and Number:
Japanese Patent JP2002534487
Kind Code:
A
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.
