Abstract
The resistance of supported Ni catalysts for carbon deactivation in CH4 partial oxidation (POM) was studied in this work. The 5%Ni/Al2O3 catalyst showed only 18% of CH4 conversion at 900 °C and 23% carbon deposition after 24 h run of POM. Both Au addition and binary support CrAl3O6 use seem to guarantee high activity (100% at 900 °C), selectivity (97% at 900 °C) and high carbon resistance (<1%). Furthermore the gold doped catalysts revealed only the presence of Cα and Cβ whereas the monometallic Ni catalysts showed the presence of graphitic carbon Cγ responsible for catalysts deactivation.
