• Resumen

  • In this study, performance of nano structure Co/γ-Al2O3 catalysts in partial oxidation of butane was investigated. The catalysts were produced through chemical reduction and incipient wetness impregnation methods. Prepared catalysts were characterized with X-ray diffraction (XRD), high resolution transmission electron microscopy (HRTEM),N2 adsorption/desorption (BET), temperature programmed reduction (TPR) and thermal gravity analysis (TGA). The characterization results confirmed the uniform dispersion of Co nanoparticles over γ-Al2O3 by using chemical reduction. Butane conversion, H2 and CO selectivities increased by decreasing of Co particle size due to higher dispersion and reducibility. The optimum value of H2/CO ratio of 2 obtained from chemical reduction technique. The results showed that the stability of catalyst produced by chemical reduction method was higher than incipient wetness impregnation ones.
