Title
(EN) METHOD FOR THE PRODUCTION OF CONJUGATED POLYUNSATURATED FATTY ACIDS WITH HETEROGENOUS CATALYSTS
(FR) PROCÉDÉ POUR LA PRODUCTION D'ACIDES GRAS POLYINSATURÉS CONJUGUÉS AVEC DES CATALYSEURS HÉTÉROGÈNES
Abstract
(EN)
The present invention relates to an improved process for the production of conjugated polyunsaturated fatty acids (PUFA), preferably conjugated linoleic acid (CLA), using finely dispersed heterogeneous metal catalysts on a mesoporous support, in the absence of Hg. The present invention also relates to a method to increase the large microporosity and (optionally) the small mesoporosity of a zeolite, thus obtaining a modified zeolite having a large and highly accessible internal surface.
(FR)
La présente invention porte sur un procédé perfectionné pour la production d'acides gras polyinsaturés (AGPI) conjugués, de préférence d'acide linoléique conjugué (ALC), à l'aide de catalyseurs métalliques hétérogènes finement dispersés sur un support mésoporeux, en l'absence d'Hg. La présente invention porte également sur un procédé pour augmenter la grande microporosité et (éventuellement) la petite mésoporosité d'une zéolite, ce qui permet d'obtenir ainsi une zéolite modifiée ayant une surface interne importante et hautement accessible.
