Abstract

Abstract In this study, performance of Ni/γ-Al2O3 catalysts which is prepared under the influence of magnetic field (MF) was investigated in partial oxidation of methane (POM) reaction to syngas. The results showed that the Ni based catalyst which was prepared by calcinations with the MF, as compared with ordinary calcinations, increased in CO selectivity and H2 yield. Based upon XRD and TEM characterization results, a catalyst that was prepared by calcinations with MF, the average size of particles decreased from 4–12 to 2–8 nm, showing the effect of MF in improved dispersion of Ni oxide catalysts. Also, the TGA characterization demonstrated enhanced anti-carbon deposit ability
