New micro and mesoporous materials for the reaction of methanol to olefins

(1) We will show that nano sized samples of SAPO-34 synthesized by microwave heating presents much higher lifetime than standard-SAPO-34 synthesized by conventional hydrothermal method for the reaction of methanol to olefins. (2) We will stabilize the Nano SAPO-34 in the ways such as steaming with water or calcinated in H2 condition. (3) The treatment of mix alkali treatment with proper TPAOH/NaOH could make composites with mesopore and microporous structure in the zeolite ZSM-5 to reduce strong acid quantity and the change the selectivity of the main product. (4) Different 8MR zeolite show different selectivity and lifetime in the same condition in the reaction of methanol to olefins.Li, Z. (2014).
