Abstract: A process for preparing a monolithic catalysis element includes a fibrous support and a catalytic phase supported by the fibrous support and also the monolithic catalysis element. The process includes the steps of preparing a porous coherent structure based on refractory fibers; preparing a substrate including the porous coherent structure and nanocarbon supported by the porous coherent structure in the body thereof; and grafting to the substrate, by ? interaction, of at least one aromatic compound containing in its chemical formula, at least one aromatic ring, and at least one function chosen from acid catalytic functions, basic catalytic functions, metallic precursor functions, functions that can be converted in situ into metallic precursor functions, and mixtures thereof.
