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.

One of the most important tasks of modern refineries is the modernization of existing plants to increase production and improve the quality of the commodity. In this connection, the catalytic activity of the industrial catalyst of the reforming pro- cess R-98 (containing in its composition platinum and rhenium, in the amount of 0.25% by weight of each) in the conversion of a stable catalyst was studied. Stable catalyst is released from the stabilizer column of the catalytic reforming unit.
