A method for forming packing for resin catalytic packed beds (12), comprising: providing elastic means (1) which are capable of compressing under the pressure applied by resin particles (11) which expand upon contact with a specific work substance, and have characteristics of elasticity and resiliency which are adapted for the expansion factor of the resin; preparing a packing constituted by a mixture of particles (11) of resin and of elastic means (1), mixed in proportions which are selected as a function of the degree of expansion; and loading the packing (5) so as to constitute an elastic catalytic packed bed (12) which is adapted to remain dimensionally stable following the expansion of the resin particles (11) and allow an easy flow of the substance through the catalytic packed bed (12). The packing thus formed comprises a mixture (5) of particles of resin, which can expand upon contact with a specific work substance and elastic means (1) adapted to compress under the pressure applied by the expanding particles and is constituted by proportions of particles (11) and elastic means (1) which are selected as a function of the resin expansion factor.

L'invention concerne un procédé de formation de garniture pour lits de résine garnis catalytiques (12). Le procédé consiste à mettre en oeuvre des moyens élastiques (1) pouvant être comprimés sous l'effet de la pression exercée par des particules de résine (11) qui gonflent au contact d'une substance de travail spécifique et présentent des caractéristiques d'élasticité et de résilience adaptées pour le facteur de dilatation de la résine. Le procédé consiste ensuite à: préparer une garniture constituée d'un mélange de particules (11) de résine et de moyens élastiques (1) mélangés selon des proportions choisies en fonction du degré de dilatation; et charger la garniture (5) de façon à constituer un lit garni catalytique (12) adapté pour garder des dimensions stables consécutivement à la dilatation des particules de résine (11), et pour permettre un écoulement facile de la substance à travers le lit garni catalytique (12). La garniture ainsi formée comprend un mélange (5) de particules de résine pouvant gonfler au contact d'une substance de travail spécifique et de moyens élastiques (1) adaptés pour se tasser sous l'effet de la pression exercée par les particules dilatées. Ele est constituée de proportions de particules (11) et de moyens élastiques (1) choisies en fonction du facteur de dilatation de la résine.
