Abstract
In a previous paper (Thermochim. Acta, 233 (1994) 317) the authors pre sented their results concerning TPR, TPD and pulse hydrogen adsorption on a Ni-Cr catalyst calcined at 640-degrees-C without previous reduct ion (sample A640). This paper deals with the influence of prereduction of the same catalyst on TPR and TPD heating cycle records (HCR) and a lso on pulse hydrogen adsorption even if these catalysts had been kept in air atmosphere for six months. Our results show that the influence of prereduction is preserved.
