The activity and selectivity of model NiCu–SiO2catalysts with the high metal loading (90%) and variousNi content was studied in anisole hydrotreatment at 280◦C and a hydrogen pressure of 6 MPa in a batchreactor. To obtain the alloys with the homogeneous phase composition, the catalysts were preparedby simultaneous decomposition of metal salts with the subsequent stabilization with 10 wt% SiO2. Thecomposition of the NiyCu1−yalloy surface was estimated from the combination of XPS and XRD data. Onthe basis of obtained kinetic data, a reaction scheme of anisole conversion was proposed. The schemeincludes two parallel routes, one of which leads to CarO bond cleavage with the formation of benzene,which is then converted to cyclohexane (HDO route), while the second route leads to hydrogenation of thearomatic ring of anisole with the formation of methoxycyclohexane and cyclohexanol (HYD route). Theexperimental dependence of anisole conversion was described by the first-order kinetics with respect tothe reagents. The effect of the surface composition of the active phase NiyCu1−yon the specific catalyticactivity was examined. According to the proposed reaction scheme, the dependence of the first-order rateconstants for both routes on the nickel content in the active component of the catalysts was determined.The selectivities of both reaction routes of anisole conversion (HDO and HYD) were found to be indepen-dent of the Ni content except for the nickel-rich and copper-rich sides. The specific catalytic activity inthe HDO route rises with an increase in the nickel content in the whole range of Ni loading.
