Conclusions

li1.

  1. 2.

    Hydrogen is adsorbed on the catalysts in question in molecular and dissociated forms. The activation energies of various forms of the adsorption of hydrogen are determined.

  2. 3.

    Hydrogen, desorbed in high-temperature forms in a 300–550° C interval, participates in the hydrodesulfurization reaction of thiophene. The reaction of H2 with thiophene on the surface of the Al2O3- CoO-MoO3 catalyst is facilitated in the presence of an Al2O3 carrier.
