Influences of Reaction Conditions on Ethene Conversion to Propene over SAPO-34

Abstract

Abstract: Ethene conversion to propene was carried out over SAPO-34. The influences of reaction conditions on the catalytic performance were investigated in detail. It was found that the propene selectivity increased with space velocity. Ethene conversion decreased with reaction temperature, whereas the selectivity for methane and ethane increased. At the same level of ethene conversion the propene selectivity decreased with reaction temperature. An obvious induction period was observed in the ethene conversion over SAPO-34, and it was strongly influenced by the reaction conditions.

Key words: SAPO-34 molecular sieve, ethene, propene, coke deposition, induction period
