fischer–tropsch synthesis with cu-co nanocatalysts prepared using novel inorganic precursor complex

The structural properties and activities of cu-co catalysts used in fischertropsch synthesis are explored according to their method of preparation. impregnation, coprecipitation, and a novel method of thermal decomposition were applied to an inorganic precursor complex to generate the cupromoted alumina and silicasupported cobalt catalysts. the precursors and the catalysts obtained by their calcination underwent powder xray diffraction, thermal gravimetric analysis, specific surface area measurement using the brunaueremmettteller method, scanning electron microscopy, and fourier transform infrared (ftir) spectroscopy. the catalytic performance of all calcined catalysts used in fischertropsch synthesis was investigated at 280 to 360 °c. the cu-co/sio2 catalyst was prepared by thermal decomposition of [cu(h2o)6][co(dipic)2].2h2o/sio2, which served as an optimal precursor for synthesis gas conversion into light olefins. the results highlight the advantages of this novel procedure over impregnation and coprecipitation approaches for effective and durable preparation of cobalt catalysts for fischer-tropsch synthesis.
