A process for catalytically dehydrogenating an anthrahyquinone to form anthraquinone and a hydrogen product. A catalyst which is a metal, a metal compound or a metal or metal compound dispersed on a support or is a liquid is selected to have an electronegativity greater than about 2.30 so as to result in the substantially complete conversion of anthrahydroquinone to anthraquinone and hydrogen and thereby essentially eliminate formation of unwanted hydrogenolysis by-products, such as anthrones and or anthranols.
Procédé de déshydrogénation catalytique d'une anthrahydroquinone permettant de former de l'anthraquinone et un produit d'hydrogène. Un catalyseur qui est un métal, un composé métallique ou un métal ou composé métallique dispersé sur un support ou encore un liquide, est choisi de façon à présenter une électronégativité supérieure à environ 2,30, ce qui entraîne une conversion sensiblement complète de l'anthrahydroquinone en anthraquinone et hydrogène, et permet de supprimer essentiellement la formation de sous-produits d'hydrogénolyse indésirables, tels que les anthrones et/ou des anthranols.
