The present invention provides a kind of propylene catalyst for producing, it is characterized in that, for from selected from methanol, dimethyl ether and carbon atom number be 4~8 alkene in one kind or two or more manufacture propylene, the catalyst is made of the adhesive-free crystalline aluminosilicate formed body that silicon/al atomic ratio is 500~10000, crystalline aluminosilicate includes the crystal structure of MFI type crystal structure and/or MEL type, by using the propylene catalyst for producing, then the paraffinic components such as ethylene, propane, the production quantity of aromatic component are few, and propene yield, propylene/propane ratio, catalyst life are excellent. |
