Abstract
The results for synthesis and study of composite cobalt catalyst for direct production of liquid hydrocarbons from CO and H2 are presented. The composite system was obtained on the basis of industrial long-chain hydrocarbon synthesis catalyst Со-Al2O3/SiO2 and commercial HZSM-5 zeolite. The catalyst was characterized by X-ray energy dispersive spectroscopy, X-ray diffraction, temperature-programmed reduction, BET. The comparative characteristics for a bifunctional composite and Fischer-Tropsch synthesis catalysts are presented. The composite catalyst shifts the distribution of the C5+ hydrocarbons towards formation of gasoline fraction at the cost of heavy waxes and diesel fraction hydrocracking. The octane number of the resultant gasoline and the cetane number of diesel engine fuel fraction were estimated by research method and amounted respectively to 92 and 48.
Keywords: Fischer – Tropsch synthesis; composite catalyst; zeolite; hydrocracking; synthetic; hydrocarbon motor fuels
