In this article, the ZSM-5 catalyst was used as the base catalyst and its structure was modified for conducting Methanol to Gasoline reactions. ZSM-5 catalyst reacts to the solutions with diverse concentrations of calcium carbonate (CaCO3) and sodium carbonate (Na2CO3), and consequently, some changes were applied to its internal structure. Thus, Methanol to Gasoline (MTG) process was carried out under pressure of 1 atm, the temperature of 400°C, and specific surface area of 300 m2g-1 on synthetic zeolite ZSM-5 catalyst by a fixed-bed reactor. Structure and morphology of the synthesized catalyst were investigated by XRD, FT-IR, SEM, XRF and BET analyses. The effect of CaCO3 and Na2CO3 solutions used for catalyst modification on the distribution of hydrocarbon products were studied and compared to ZSM-5 catalyst. The result of catalyst activity evaluation tests shows that the modified catalyst with a 0.1 molar solution of CaCO3 and Na2CO3 provides the highest selectivity and efficiency compared to the hydrocarbons in boiling point range of C6+ gasoline.

In this article, the catalytic conversion of methanol to gasoline range hydrocarbons has been studied over CuO/ NH4‐ZSM‐5(3,5,7,9%) catalysts prepared via sono‐chemistry methods. In order to improve, copper oxide can be used as a booster on NH4‐ZSM‐5 this catalyst property. Accordingly, the conversion process of Methanol to Gasoline (MTG) was conducted under a pressure of 1 atm and temperature of 400°C by a fixed‐bed reactor on copper oxide catalysts which were prepared based on synthetic NH4‐ZSM‐5. The synthetic catalyst was investigated by such analyses as BET, XRD, FT‐IR, and SEM. Formation of copper oxide phase and proper distribution of copper oxide were proven on the basic level of using XRD analysis. BET analysis showed the reduction in catalyst level and SEM images depicted the proper distribution of particles. The present investigation is to study the effect of CuO loading on NH4‐ZSM‐5 support for conversion of methanol to gasoline range hydrocarbons. A series of CuO/ NH4‐ZSM‐5 catalysts were prepared, characterized, and experimented for their performance on methanol conversion and hydrocarbon yield.
