(FR) CATALYSEUR POUR LA DÉSHYDROGÉNATION DE PARAFFINE
Abstract
(EN)
Rare earth element containing catalysts for dehydrogenating paraffins and the methods of making the catalysts are disclosed. A rare earth modified alumina support in eta-alumina form, theta-alumina form, or combinations thereof is impregnated with chromium-containing solution. The chromium-impregnated support is then subjected to calcination processes. The produced catalyst contains the rare earth element, chromium, and alumina. The crush strength of the produced catalyst is greater than 0.4 daN/mm.
(FR)
L'invention porte sur des catalyseurs contenant un élément de terres rares qui permettent de déshydrogéner des paraffines et sur les procédés de fabrication des catalyseurs. Un support en alumine modifiée par des terres rares sous forme d'eta-alumine, de thêta-alumine ou de combinaisons de celles-ci, est imprégné avec une solution contenant du chrome. Le support imprégné de chrome est ensuite soumis à des procédés de calcination. Le catalyseur produit contient l'élément de terres rares, le chrome et l'alumine. La résistance à l'écrasement du catalyseur produit est supérieure à 0,4 daN/mm.
