| 英文摘要 | temperature-programmed surface reaction-mass spectrometry (tpsr-ms) and temperature-programmed desorption (tpd) techniques were used to study the relationship between the catalytic activity of sapo-34 and sapo-44 molecular sieves for methanol to olefin (mto) reaction and their acidity. the result showed that there were two kinds of active sites on sapo-34 and sapo-44 molecular sieves, which were corresponding to the acidic sites with different strength on the molecular sieves. the adsorbed methanol underwent different reactions on different acidic sites. methanol converted to dimethyl ether on the weak acidic sites, and light olefins were formed mainly from the adsorbed dimethyl ether on the strong acidic sites. the effect of the acid site strength on the light olefin formation temperature was also elucidated. |
