Comparative study of CHA- and AEI-type zeolytic catalysts for the conversion of chloromethane into light olefins
Three pairs of CHA- and AEI-type zeolytic materials with similar crystallite size but with different framework atoms, i.e., silicoaluminophosphate SAPO-34 and SAPO-18, aluminosilicate SSZ-13 and SSZ-39, and titaniumincorporated TiAPSO-34 and TiAPO-18, were prepared and their catalytic activities of chloromethane into light olefins were compared according to the structure types, as well as acidic properties. The AEI-type catalysts were found to have lower ethene/propene ratios, indicating relatively higher propene selectivity, because their aei-cage was larger compared to the cha-cage. However, all the CHA-type catalysts exhibited better activity and higher selectivity to light olefins. Both H-SAPO-34 and H-TiAPSO-34 showed good catalytic stability over all the reaction times studied here. When compared to H-SAPO-34, however, H-TiAPSO-34 exhibited ca. 20mol% higher selectivity to ethene and propene, despite a similar total density of acid site. This performance may be due to the higher strength of medium acid sites.
