Abstract

L'invention concerne une structure améliorée de catalyseur et son utilisation pour des processus hautement exothermiques, tels que la combustion catalytique. Cette structure améliorée de catalyseur assure un échange thermique intégral grâce à un agencement de passages ou de canaux de réaction adjacents, qui sont disposés longitudinalement et qui sont soit chargés de catalyseur (14) ou exempts de catalyseur (16), la configuration des canaux chargés de catalyseur (14) différant de celle des canaux sans catalyseur (16) pour que, lorsqu'on met en oeuvre des réactions exothermiques, telles qu'une combustion catalytique, la réaction souhaitée est favorisée dans les canaux catalytiques (14) et sensiblement limitée dans les canaux non catalytiques (16). L'invention concerne en outre un système et un procédé réactionnels améliorés pour la combustion catalytique d'un carburant faisant appel à un échange thermique intégral, de préférence avec la structure améliorée de l'invention, où un produit gazeux partiellement brûlé passe dans une zone de combustion homogène, dans laquelle une combustion complète est assurée par un stabilisateur de combustion.
