Abstract: The present invention relates to zeolite adsorbents based on agglomerated crystals of zeolite EMT comprising barium and/or potassium. These adsorbents find applications in the separation of aromatic C8 isomer fractions, especially of xylenes, in the separation of substituted toluene isomers, such as nitrotoluene, diethyltoluene and toluenediamine, and in the separation of cresols, and in the separation of polyhydric alcohols, such as sugars.

Abstract: The present invention relates to zeolitic adsorbents based on agglomerated crystals of FAU zeolite containing barium and/or potassium, with large external surface area, combining optimum properties in terms of selectivity and mechanical strength. These adsorbents find applications in the separation of cuts of C8-aromatic isomers and notably of xylenes, in the separation of isomers of substituted toluene such as nitrotoluene, diethyltoluene, toluenediamine, in the separation of cresols, and in the separation of polyhydric alcohols such as sugars.

Abstract: The invention relates to an oxygen carrier solid, its preparation and its use in a method of combustion of a hydrocarbon feedstock by active mass chemical-looping oxidation-reduction, i.e. chemical-looping combustion (CLC). The solid, which is in the form of particles, comprises an oxidation-reduction active mass composed of metal oxide(s) dispersed in a ceramic matrix comprising at least at least one feldspar or feldspathoid with a melting point higher than 1500° C., such as celsian, and has, initially, a specific macroporous texture. The oxygen carrier solid is prepared from a precursor of the ceramic matrix, obtained from a macroporous zeolitic material with zeolite crystals of a specific size, and a precursor of the oxidation-reduction active mass.
