Five different signals have been analyzed in ESR spectra obtained from sulfided molybdenum- or tungsten-containing catalyst samples. Signal I (oxo-Mo5+, g = 1.933 for Mo/γ-Al2O3; and oxo-W5+, g = 1.78 for W/γ-Al2O3), and possibly signal III arise a

Laser Raman spectroscopy is used to study the structure of molybdenum and cobalt species present in CoMo γ- Al 2 O 3 catalyst systems. From comparison with Raman spectra of Mo and Co in known structures it is derived that these catalyst systems c

ESR spectra of nickel- or cobalt-promoted sulfided tungsten- or molybdenum-containing catalysts are measured together with the influence of equilibration at different H2SH2 ratios and CO adsorption hereon. The ESR measurements are compared with thiop

Hydrodesulfurization catalysts were prepared by impregnating silica and alumina with aqueous solutions of thioheteroanion complexes containing Ni or Co and Mo or W. Their catalytic activities are comparable to those of conventionally prepared catalys
