摘要:A palladium catalyst supported by SAPO-5 molecular sieve was obtained by direct cocrystallization from a SAPO-5 gel mixture and a palladium salt, which has been compared with a Pd/SAPO-5 catalyst formed by conventional impregnation method. The PdSAPO-5 catalyst was found to have the characteristics of high and even dispersion of palladium, modification of the acidic sites on SAPO-5 by the introduced Pd, and higher activity and selectivity for methanol conversion. A catalytic site comprising a Bronsted acid site and an adjacent Pd is proposed.
