Abstract: A method of manufacturing a sorbent material is described, to include mixing a first granular material containing iron and a second granular material containing aluminum hydroxide. The first granular material and the second granular material are mixed in a proportion such that a ratio of Fe to Al is between 0.5 and 3.5 by weight. The second granular material has an Al content (including aluminum hydroxide phases) of at least 30% by weight. The mixture is subjected to a thermal treatment at a temperature between 400° C. and 950° C. to obtain a sorbent material comprising a first phase rich in iron oxides bound by a matrix rich in aluminum oxide, and the obtained sorbent material has a compressive strength of at least 3 MPa.
