“…He found that similar satellite reflections appear in the beginning stage of the interaction (470 K) of equimolar C 2 H 2 -H 2 mixture with pure Ni powder, and the reflections were attributed to formation of a solid solution of carbon in nickel fcc phase, NiC x . Moreover, he found that during a prolonged interaction of C 2 H 2 -H 2 mixture with nickel the satellite reflections vanished and the reflections characteristic of Ni 3 C hcp phase appeared [8][9][10][11]. As regards our work results, no traces of reflections of Ni 3 C phase were found.…”

“…A well known case of such changes is carbonisation of metal catalysts in the course of various reactions involving carbon containing reactants. In the case of nickel catalysts, various carbon containing forms appear, such as carbon deposits [2][3][4][5][6][7], stoichiometric nickel carbide [8][9][10][11][12] and sometimes concentrated solutions of carbon in nickel phase [13,14]. The subject of this communication is the carbonisation of nickel which occurs during CO hydrogenation over potassium promoted Ni/Al 2 O 3 catalyst.…”

“…the C-C rupture is caused by hydrogen (Equation 3) and not by a free site or adsorbed hydrogen. The first-order kinetics of Equation (3) is in agreement with Galwey (1962). 4.: The negative entropy change (AS) for ethane and hydrogen (Equation 2) is understandable since the adsorption of gaseous ethane and hydrogen results in a more ordered structure. 5. : The values of the bond energies between the adsorbed gases and the catalyst surfaces are also listed (E (Ni-H) Kristyan (1985) Eq.…”

“…Galwey (1962) demonstrated that on heating pure nickel carbide in excess H2 at 525 K, methane and ethane were formed in the ratio 1:0.05, and no other products were detected. In contrast, hydrogenation of adsorbed C coating Fe-based systems yields a broad distribution of products with a wide range of molecular weights, including alkenes (Kolbel and Tillmetz, 1974).…”
