Abstract: The reactivation of the waste commercial Ni/Al2O3 catalyst used in reforming ofmethane or natural gas by carbon dioxide has been studied on a fixed-bed flow apparatus byusing XRD and TPR techniques;It is found that if the waste catalyst is first reduced at1193K,then treated with 20% aqueous hydrogen peroxide solution(disperser),the activitycould be renewed to that of the fresh one.

Key words: alumina supported nickel, catalyst, synthetic gas, regeneration
