Liquid products of thermal treatment of organo-mineral sludge: Chemical characterization and fuel properties

This study presents the results of a comprehensive investigation of liquid products obtained during the thermal treatment of organo-mineral sludge. The main focus is placed on determining the chemical composition, establishing fractional distribution, and evaluating the fuel characteristics of the resulting liquid fraction. A set of analytical methods, including gas chromatography, infrared spectroscopy, and elemental analysis, has been employed to provide a detailed characterization of the product.

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.
