Abstract The study investigates the effects of nickel introduction methods on the properties of a hybrid cobalt catalyst in a combination of Fischer–Tropsch synthesis and the hydroprocessing of the synthesized products. At 240°C, 2 MPa, and syngas WHSV 1000 h–1, the catalytic performances were compared, the products were analyzed for the hydrocarbon and fractional compositions, and the characteristics of the synthesized fuels were determined. Among the catalysts differing in nickel introduction method, the sample with a nickel-containing zeolite component prepared by ion exchange was found to have the highest hydrogenation activity, while the sample with a metal component generated by joint cobalt/nickel introduction [Co/SiO2 + Ni(i)/HZSM-5 + Al2O3] exhibited the highest isomerization activity.

Un-promoted and promoted Co/SiO2 catalysts with ZrO2 and Ru were prepared and the catalytic performances for Fischer-Tropsch synthesis were investigated. The prepared catalysts were characterized by XRD, N2 adsorption/desorption, and X-ray absorption techniques. XRD suggested that the cobalt species presence in all prepared catalysts was Co3O4. Promoted catalyst with ZrO2 and Ru showed high distribution of cobalt on silica surface resulted in smaller Co3O4 crystalline size than un-promoted ones. From the reaction testing, the obtained products of C1 to C9 from un-promoted and promoted Co/SiO2 were studied.
