Eff ect of the MoO3/Al2O3 catalyst fl uorination on the propylene metathesis reaction

In the course of this work, fl uorinated catalysts MoO3 /Al2 O3 -F for the olefi ns metathesis have been synthesized. The materials have been characterized by various physicochemical methods and tested in the propylene metathesis reaction. It has been shown that the support fl uorination leads to partial replacement of surface hydroxyl groups by F, which is accompanied by an increase in the strength of both Lewis acid sites and residual bridging OH groups. Increasing the fl uorine content on γ-Al2O3 up to 3 wt.

Catalytic Conversion of Ethyl Alcohol on Zeolite Catalysts

This article describes the possibility of using bioethanol as a substitute for conventional fuel from petroleum feedstocks. Bioethanol obtained by fermentation from biomass is considered not only as an analogue of gasoline or a fuel additive, but also as a source of raw materials for the production of olefins, aromatic hydrocarbons and gasoline range hydrocarbons by means of catalytic conversion. At present, it is believed that the conversion of ethanol on zeolites proceeds in several stages.
