The Research of Diluents Added to HZSM-5 on the Methanol to Gasoline Reaction

Abstract

The performance of methanol to gasoline (MTG) reaction was apparently influenced by the addition of diluents to ZSM-5. The lifetime of catalyst was prolonged when appropriate amount of diluents was added into the catalyst. The yield of MTG oil improved with the addition of diluents, while the initial conversion of methanol decreased slightly，and the total amount of oil product increased. At the same time, the content of dimethyl ether (DME) and light olefins obviously increased when large amount of diluents was added into the catalyst.
