Abstract

On nickel‐alumina catalysts, the hydrogenation of carbon dioxide into methane is more rapid than that of carbon monoxide due to much slower de‐activation of the catalysts in the presence of the mixture (CO~2~ + H~2~). Under the same conditions, competitive hydrogenation of CO and CO~2~ leads to intermediate results which are, nevertheless, close to those obtained with the mixture (CO + H~2~) due to significant CO adsorption.

In this work, pillared clays as Co catalysts supports were studied in the CO hydrogenation called Fischer-Tropsch (FT) reaction. Two supports were prepared by different methods [K. Sapag, Ph.D. Thesis, Universidad Autónoma de Madrid, 1997, Madrid, Spain] with the same metal/clay ratio. They were im
