摘要：
In a previous paper (Thermochim. Acta, 233 (1994) 317) the authors presented their results concerning TPR, TPD and pulse hydrogen adsorption on a Ni-Cr catalyst calcined at 640-degrees-C without previous reduction (sample A640). This paper deals with the influence of prereduction of the same catalyst on TPR and TPD heating cycle records (HCR) and also 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.
