Hydrocarbon Synthesis from Dimethyl Ether Over ZSM-5 Catalyst
The liquid phase synthesis of dimethyl ether from syngas has significant advantages over the liquid phase methanol synthesis in the areas of syngas conversion and reactor productivity. The merits of this dual catalytic process a!lows dimethyl ether to be utilized as a viable feedstock for petrochemical synthesis. In particular, dimethyl ether can be converted to hydrocarbons using H-ZSM-5 type zeolite catalysts. Appropriate choice of the acidity of the zeolite catalyst as well as the operating parameters such as reaction temperature, partial pressure and space velocity of dimethyl ether dictate the product spectrum, ranging from lower olefins (ethylene and propylene) to gasoline-range hydrocarbons. The focus of this paper is to thoroughly study the aforementioned details of this process and compare its merits with methanol conversion.
