Аннотация:Bioethanol is a perspective renewable motor fuuel. But, to be more effective and have a broad perspectives for applications, it needs to be converted to hydrocarbons. MFI (aluminosilicate zeolites of the pentasil family, Si/Al = 30) zeolite showed especially high activity in the conversion of ethanol to aliphatic and aromatic hydrocarbons C3-C12. Since the main problem of its use in industrial scale is the fast coking followed by activity loss, we present the new study that demonstrates the possibility to operate in stable conditions during 100 hours. An original Au-Cu/Al2O3/MFI catalyst was developed that provides high activity (ethanol conversion 100% at 330oC) and selectivity (aim products yield – 96%) in ethanol conversion to hydrocarbons C3-C12. Catalyst operation method was suggested that provides stable work during at least 100 h with intermediate regeneration with water vapor treatment followed by reduction with hydrogen.
