Recent advances in Methanol-to-Gasoline technology and related catalysts

The technology of Methanol-to-Gasoline can alleviate the shortage of domestic oil and the overcapacity of methanol production. This paper was aimed to introduce the process of Methanol-to-Gasoline，including fixed bed and fluidized bed technology. The technology features were described briefly. Present situation of catalyst was introduced. The effect of alkali treatment and metal modification on the structure and catalytic properties of ZSM-5 was highlighted. The development goal of Methanol-to-Gasoline catalyst is to obtain higher specific surface area and higher stability. The reasons for deactivation of the catalyst and catalytic mechanism of Methanol-to-Gasoline were also discussed.
