Synthesis of CON-type Zeolites with Trivalent Heteroatoms and Their Catalytic Application for MTO Reaction

Aluminum or gallium containing-CIT-1, denoted by [Al,B]- or [Ga,B]-CIT-1, have successfully been synthesized by the direct synthesis method.  [Al,B]-CIT-1 showed a long catalytic life for the MTO reaction in comparison with [Al]-beta and the main product was propene with the selectivity of 60% in the initial stage.
