Abstract
(EN)
The present invention relates to a solid catalyst, its preparation and its application. The solid catalyst of this invention is based on a solid complex material comprising a film of aluminium oxide on the surface of metal aluminium or aluminium alloy, or aluminium oxide with a defective halite type structure. The catalyst of this invention can effectively activate the compounds composed of the element of carbon, hydrogen, oxygen, nitrogen, sulfur and chlorine. The catalyst can be used to effectively catalyze the reaction between nitrogen and hydrogen (the synthesis of ammonia), the decomposition of ammonia, and the reaction of nitrogen with hydrocarbons (the catalysis dehydrogenation with nitrogen as the oxidant), ammoxidation, or oxychlorination, and it can also be applied to the hydrogenation or the oxidation of the organic compound, the hydrolysis or the dehydration, and the electrolysis reaction of the synthesis of ammonia by electrolytic processes.

L'invention concerne un catalyseur solide, son procédé de préparation et son utilisation. Ce catalyseur est formé d'une matière composite solide renfermant un film d'oxyde d'aluminium recouvrant la surface de l'aluminium métal ou de l'alliage aluminium ou d'oxyde d'aluminium présentant une structure halite défectueuse. Ce catalyseur peut activer efficacement les composés contenant du carbone, hydrogène, oxygène, azote, soufre et chlore et peut être utilisé pour catalyser la réaction se produisant entre l'azote et l'hydrogène (la synthèse d'ammonium), la décomposition d'ammonium et la réaction entre un azote et des hydrocarbures (la déshydrogénation catalytique avec un azote en tant qu'oxydant), l'ammoxydation ou l'oxychloration. Il peut aussi trouver une application dans l'hydrogénation ou l'oxydation du composé organique, l'hydrolyse ou la déshydrations et la réaction électrolytique de la synthèse d'ammonium par des processus électrolytiques.
