ROLE OF NANOPARTICLE SIZE ON PERFORMANCE OF PARTIAL OXIDATION OF BUTANE PROCESS TO SYNGAS

ABSTRACT 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),...
