摘要: Abstract: Surface organometallic chemistry (SOMC) was applied to the selective incorporation of cobalt or tin atoms active phase molybdenum-based sulfides supported on alumina. The nature involved reactions investigated by analyzing gaseous species evolved during synthesis. resulting materials were characterized various techniques, like elemental analysis, electron probe microanalysis, X-ray diffraction, transmission microscopy, energy-dispersive spectroscopy and infrared study adsorbed CO. influence doping catalytic performance sulfide evaluated in a model reaction FCC gasoline hydrodesulfurization. Under appropriate synthesis conditions, SOMC appeared be an efficient method selectively modify phase, leading significant change catalyst selectivity hydrodesulfurization/olefin conversion.
