Studies of Methane Reforming with Carbon Dioxide on Hexaaluminates

Abstract

Abstract: In this paper, a series of Sr_1-x La_x NiAl₁₁ O₁₉ catalysts were synthesized and their chemical and physical properties were investigated by XRD, UV-DRS, H₂-O₂ titration, TPRand Py-IRtechniques. The experimental results show that the Sr_1-x La_x NiAl₁₁O₁₉ catalysts have a magnetoplumbite structure and Ni ion is shared between tetrahedral and octahedral sites of the spinel blocks, and the amount of nickel ions in the tetrahedral environment increases with the increase of x value in Sr_1-xLa_x NiAl₁₁O₁₉.

Key words: Nickel, Hexaaluminate, Methane reforming with carbon dioxide
