Реферат: A series of NiCuMo(X)/SiO2 sol-gel catalysts (X as Mo/Ni atomic ratio) has been studied in hydrotreatment of guaiacol (GUA) to clarify the effect of different Mo content on the catalysts performance in the target process. GUA conversion over NiCuMo(X)/SiO2 catalysts was shown to proceed through the two main routes: HDO and HYD route − with benzene and methoxycyclohexanoles as the main intermediates, correspondingly. Increasing of Mo content allowed higher contribution of HDO route into GUA transformations, the final product always being cyclohexane. The catalysts stability after glacial acetic acid treatment was shown to increase noticeably with Mo content. According to the catalysts characterization by physicochemical methods, their corrosion resistance and changes in HDO selectivities could be associated with the change of active component nature: electronic effects between Mo0 and Ni0, and the presence of coordinatively unsaturated Mo species, which could play a significant role in activation of Oxy-organics.
