Abstract
The invention is addressed to very light alumina-based agglomerated bodies, the porosity of which comprises pores of large dimensions. These bodies are produced from alumina gels which are dehydrated in hot gas streams so that the amount of water remaining, which can be measured by calcination at high temperature, is from 8 t0 35% of the weight of the treated gels; the treated gels to which other components can be added are agglomerated by any known means. These bodies can be used in particular in adsorption, catalysis, and chromatography.
