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.
