Hydrogenation of polyaromatics in the presence of hydrogen-hydrogen sulphide system

Fuel, 1989
Abstract Thermal production of hydroaromatics by addition of molecular hydrogen to polyaromatics was studied in the presence of hydrogen sulphide or tetralin. The results indicate the importance of wall catalytic effects related to H 2 H 2 S activity during fossil fuel treatment.

Hydrogen–hydrogen bonding: The current density perspective

Journal of Computational Chemistry, 2015
Current density plots of closed‐shell intermolecular HH interactions characterized by a bond critical point (BCP) show two vortices separated by a saddle, a pattern which allows for a clear definition of a pair current strength. This HH current strength turns out to be roughly related to the potential energy density at the BCP and then to the ...

Hydrogen storage on fullerenes: hydrogenation of C59N? using C60H36 as the source of hydrogen

Chemical Communications, 2004
C(60)H(36) has been used as the source of hydrogen for the in situ hydrogenation of (C(59)N)(2), leading to C(59)NH(5) as the main reaction product identified by negative-ion mass spectrometry and providing evidence of the usage of C(60) as a storage device for hydrogen.

Hydrogenation by hydrogen bronzes I. Hydrogenation of ethylene by HxMoO3

Journal of Catalysis, 1982
Abstract Hydrogenation of ethylene has been studied on hydrogen molybdenum oxide bronzes prepared by spillover of hydrogen from supported Pt particles. The temperature of the formation and of the outgassing of the bronze, as well as the Pt content, was found to influence the rate of the reaction of ethylene.

Hydrogenation by hydrogen bronzes II. Hydrogenation of ethylene by HxV2O5

Journal of Catalysis, 1984
Abstract Hydrogen vanadium oxide bronzes have been prepared by spillover of hydrogen from supported Pt particles. The crystallinity of the starting oxide disappears progressively during the insertion of hydrogen so that a bronze with an initial stoichiometry of about H 3.3 V 2 O 5 is quasi-amorphous.
