Reactions were carried out with the electrolytic hydrogen from the balloon (99.8%), for the gas liquid chromatography (GLC) was used helium (99.992%) from a cylinder. The alcohols and hexane of mark “chemically pure” were used as solvents. Experimental conditions: amount of gasoline -5.0 or 30.0 ml, amount of catalyst within 0.5-3.0 g; 2.0-4.0 MPa hydrogen pressure, the reaction temperature-293-373 K. Theresults of experiments on reduction of gasoline fractions made out in the form of curves on rectangular coordinate system, where the horizontal axis represents experience duration in min. (τ), on the y-axis of the volume of hydrogen per cm3.
