✦ Synopsis

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 impregnated with 20% of cobalt in salt solution and calcinated to obtain the catalysts. The reaction was realised at 20 bar of pressure and temperatures between 200 and 280 • C approximately.

The results show a better selectivity to products with certain carbon chain size for one of the supports, due probably to its textural properties. This selectivity was investigated through a series of additional experiences in which different catalysts were prepared and probed, among them a FT standard catalyst.

The catalyst that shows the best results not only has good shape selectivity, besides, it also has better intrinsic activity if compared with the FT standard catalyst.

## 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~
