The resistance of supported Ni catalysts for carbon deactivation in CH(4) partial oxidation (POM) was studied in this work. The 5%Ni/Al(2)O(3) catalyst showed only 18% of CH(4) conversion at 900 degrees C and 23% carbon deposition after 24 h run of POM. Both Au addition and binary support CrAl(3)O(6) use seem to guarantee high activity (100% at 900 degrees C), selectivity (97% at 900 degrees C) and high carbon resistance (<%). Furthermore the gold doped catalysts revealed only the presence of C alpha and C beta whereas the monometallic Ni catalysts showed the presence of graphitic carbon C gamma responsible for catalysts deactivation.
