Nickel catalyst activation in the carbon dioxide reforming of methane Effect …

Abstract. A Ni/Al2O3 catalyst has been submitted to different treatments prior to catalytic test in the dry reforming of methane. The performed pretreatments are: (i) calcination þ hydrogen reduction, (ii) direct hydrogen reduction and (iii) heat treatment up to the reaction temperature under inert atmosphere. The activity is not affected by the pretreatment carried out but a noticeable ef…
