Highly selective formation of propylene from methanol over high-silica EU-1 zeolite catalyst

High-silica EU-1 zeolite (SiO2/Al2O3 = ~ 400) was tested in methanol to propylene (MTP) reaction and was found to be a very efficient catalyst. In comparison with the other three high-silica zeolites, i.e. ZSM-48, ZSM-5, and beta zeolites, a higher propylene selectivity (52%) and remarkably high propylene/ethylene (P/E) ratio (15) were obtained under the operating conditions of T = 450 °C, P = 0.1 MPa, and WHSV = 1.5 h− 1. Besides, a substantially low amount of C5 + hydrocarbons, especially aromatics is another prominent feature of the product distribution over high-silica EU-1 catalyst.

► High-silica EU-1 zeolite was studied in the conversion of methanol to propylene.
► This catalyst showed high propylene selectivity (52%) and high P/E ratio (15).
► Catalytic performances of EU-1, ZSM-48, ZSM-5, and beta zeolite were compared.
