Methanol to Gasoline Conversion over CuO / ZSM-5 Catalyst Synthesized and Influence of Water on Conversion

Abstract

Conversion of Methanol to Gasoline (MTG) process is accomplished by the synthesis of ZSM-5 zeolite catalyst to produce high-quality gasoline. The generated catalyst had an area of Zeolite and CuO / ZSM-5 (2%) and CuO / ZSM-5 (4%) 300 m2g-1 and 284 m2g-1 and 254 m2g-1. Structure and morphology of synthesized catalysts were studied by such analyses as BET, XRF, SEM, XRD. CuO / ZSM-5 (4%) (70% water / 30% methanol feed) catalyst resulted in increased activity for the conversion of methanol to hydrocarbons of gasoline range especially aromatics. Using (70% water / 30% methanol feed) with catalyst CuO / ZSM-5 (4%) led to improving the performance of catalysts and increased aromatic and decreased conversions. The main products of the aromatic were C7H8, (CH3)2C6H4, C8H10, CH3C6H4C2H5, C10H14, C6H4(C2H5)2, and C6H5(CH2)3CH3. Also, water on ZSM-5 and CuO / ZSM5 play an important role in the of aromatic products.
