摘要/Abstract

摘要： Hydrotalcite precursors of La modified Ni-Al₂O₃ and Ni-SiO₂ catalysts prepared by co-precipitation method and the catalytic activities were examined for the production of CO_x-free H₂ by CH₄ decomposition. Physico-chemical characteristics of fresh, reduced and used catalysts were evaluated by XRD, TPR and O₂ pulse chemisorptions, TEM and BET-SA techniques. XRD studies showed phases due to hydrotalcite-like precursors in oven dried form produced dispersed NiO species upon calcination in static air above 450 ℃. Raman spectra of deactivated samples revealed the presence of both ordered and disordered forms of carbon. Ni-La-Al₂O₃ catalyst with a mole ratio of Ni:La:Al = 2:0.1:0.9 exhibited tremendously high longevity with a hydrogen production rate of 1300 mol_H₂·mol_Ni^-1. A direct relationship between Ni metal surface area and hydrogen yields was established.
