The objective of this work was to provide comprehensive hypotheses concerning the mechanisms operative in the CN bond cleavages occurring during the catalytic conversion of amines over a conventional hydrotreating catalyst, so as to account for ex

By comparison of the hydrodenitrogenation rate of amylamine with those of neopentylamine and tert-amylamine over a conventional catalyst, it was evidenced that the hydrogen atoms of the carbon in the β position with respect to the nitrogen atom part

Unsupported MoS2 samples with surface areas ranging from 1 to 83 m2 g−1 were prepared by treatment of different precursors in a H2H2S atmosphere at 673 K. Their catalytic properties were determined for several hydrotreating reactions. Dibenzothi

The sulphidation of a nickel-tungsten catalyst has been studied by XPS and electron microscopy. These features are related to catalytic properties in test reactions characteristic of hydrotreatment (HDS, HDN, HN of aromatics) and to chemisorption mea

Alumina supported Ni-W catalysts with contents of components varying over a wide range were systematically studied in order to optimize a catalyst for further industrial use, mainly for HDN reactions. The catalytic activities were determined in diffe
The catalytic properties in pyridine hydrogenation and piperidire hydrogenolysis of molybdenum sulphide supported on alumina, silica or zirconia were determined. Significant differences on changing the support or the sulphidation temperature were obs

Catalysts containing ca.2% (w/w) of ruthenium were prepared by using [Ru(NH 3 ) 6 ]Cl 3 as a precursor compound and HY, NaY and KY zeolites as supports. Ru/KY catalyst modified by Na 2 S via impregnation was also investigated. Prior to the catalytic

Catalysts of ruthenium sulfide, dispersed in a series of Y zeolites with various acidic properties, were prepared by ion exchange and subsequent sulfidation. The activities for the reactions of hydrogenation of tetralin and toluene, carried out in th
