| 英文摘要 | hsapo-34 molecular sieve was employed in chloromethane conversion and showed high performance in activity and selectivity in production of light olefins. our detailed ir investigation allowed the identification of the active sites and the adsorbed species and demonstrated that the conversion started from 350 degrees c with alkoxy group as the intermediate. the fixed-bed catalytic testing evidenced that in the range of 350-500 degrees c, 70-80% of chloromethane was transferred to ethylene, propylene and butenes. increasing reaction temperature favors the conversion and enhances the yield of lighter olefins. a very important reversible phenomenon, the breaking of al-o-p bonds upon adsorption of hcl, a main product of reaction to generate a large amount of p-oh groups and the recovery of al-o-p upon removal of hci was revealed.
