Abstract

Préparation d'un catalyseur perfectionné à base d'argent, destiné à l'oxydation de l'éthylène à l'aide d'oxygène moléculaire, consistant à imprégner un support poreux avec un sel d'argent d'un néoacide, à soumettre le support imprégné à une activation à basses températures en le chauffant à une température comprise entre 250 et 300 DEG C, sur un tapis roulant, dans une atmosphère contenant moins d'oxygène que l'air, puis à imprégner le support avec un métal alcalin, de préférence du césium.
