Abstract

Un support de catalyseur constitué de particules d'alumine .alpha. relativement grosses dispersées dans une matrice d'alumine .alpha. formée in situ par une technique sol-gel, présente une excellente résistance à l'écrasement tout en conservant une bonne porosité ainsi qu'un bon rendement catalytique.
