Реферат: A physicochemical study of cobalt-containing (10 wt %) silica-supported Fischer-Tropsch catalysts was carried out. The catalysts were obtained under subcritical conditions (T = 200 degrees C, P = 8 MPa) using water (T-c = 374.1 degrees C, P-c = 22.1 MPa) and propanol-2 (T-c = 235.6 degrees C, P-c = 5.8 MPa). The obtained samples were compared with a 10 wt % Co/SiO2 catalyst prepared by incipient-wetness impregnation. Comparison of the properties of catalysts in the liquid-phase Fischer-Tropsch synthesis showed that the sample prepared in subcritical water was the most active and selective to aliphatic C-6-C-7 hydrocarbons. This sample is characterized by a high surface area (131.7 m(2)/g), a uniform distribution of particles in the active phase with an average size of 5 nm and higher accessibility of cobalt species for reagents. According to XPS data, the composition of catalyst active phase is mainly represented by two compounds: Co(OH)(2) and Co3O4.
