Реферат: Cermet CoZr/AlOx(OH)y/Al catalysts containing different amounts of the active component, the CoZr nanocomposite, were studied in Fischer–Tropsch synthesis (FTS). The CoZr nanocomposite was prepared by mechanochemical treatment of metallic Co and Zr powders. The cermet catalysts were obtained by mixing the CoZr nanocomposite powder with aluminum powder, followed by hydrothermal treatment. A disproportionate increase in the efficiency of the active component was observed with an increase in its content in the cermet. It was shown that in the catalyst with a higher content of the active component, the CoZr nanocomposite, the amount of aluminum hydroxo compounds (products of aluminum oxidation by water that block the cobalt surface on CoZr particles) is lower. The selectivity to the main syngas conversion products remained unchanged regardless of the fraction of the CoZr nanocomposite in the cermet. A comparison was made between the performance of the studied catalysts and oxide and cermet FTS catalysts known from the literature in terms of C5+ hydrocarbon production.
