Title (EN) ACIDIC ZIRCONIUM HYDROXIDE
(FR) HYDROXYDE DE ZIRCONIUM ACIDE
Abstract:
(EN) This invention relates to azirconium hydroxideor zirconium oxide comprising, on an oxide basis, up to 30wt% of a dopant comprising one or more of silicon, sulphate, phosphate, tungsten, niobium, aluminium, molybdenum, titanium or tin, and having acid sites, wherein the majority of the acid sites are Lewis acid sites. In addition, the invention relates to a catalyst, catalyst support or precursor, binder, functional binder, coating or sorbent comprising the zirconium hydroxide or zirconium oxide. The invention also relates to a process for preparing zirconium hydroxide, the process comprising the steps of:(a) dissolving a zirconium salt in an aqueous acid, (b) addingone or more complexing agents to the resulting solution or sol, the one or more complexing agents being an organic compound comprising at least one of the following functional groups: an amine, an organosulphate, a sulphonate, a hydroxyl, an ether or a carboxylic acid group,(c)heating the solution or sol formed in step (b), (d) adding a sulphating agent, and(e) adding a base to form a zirconium hydroxide, and(f) optionally adding a dopant.
(FR) La présente invention concerne un hydroxyde de zirconium ou un oxyde de zirconium comprenant, sur une base d'oxyde, jusqu'à 30 % en poids d'un dopant comprenant un ou plusieurs éléments parmi le silicium, le sulfate, le tungstène, le niobium, l'aluminium, le molybdène, le titane ou l'étain, et ayant des sites acides, la majorité des sites acides étant des sites acides de Lewis. De plus, l'invention concerne un catalyseur, un support ou un précurseur catalyseur, un liant, un liant fonctionnel, un revêtement ou un sorbant comprenant l'hydroxyde de zirconium ou l'oxyde de zirconium. L'invention concerne également un procédé de préparation d'hydroxyde de zirconium, le procédé comprenant les étapes consistant à : (a) dissoudre un sel de zirconium dans un acide aqueux, (b) ajouter un ou plusieurs agents complexants à la solution ou le sol résultant, le ou les agents complexants étant un composé organique comprenant au moins l'un des groupes fonctionnels suivants: une amine, un organosulfate, un sulfonate, un hydroxyle, un éther ou un groupe acide carboxylique, (c) chauffer la solution ou le sol formé à l'étape (b), (d) ajouter un agent de sulfatation, et (e) ajouter une base pour former un hydroxyde de zirconium, et (f) ajouter éventuellement un dopant.
