Les fondements structurels des r\u00e9actions catalytiques avanc\u00e9es.<\/strong><\/p>\n\n\n\n Dans l'industrie p\u00e9trochimique et de la chimie fine, le charbon actif ne sert pas d'adsorbant, mais de support structurel pour les r\u00e9actions catalytiques. Des m\u00e9taux pr\u00e9cieux \u2014 le platine, le palladium, le rhodium \u2014 sont dispers\u00e9s \u00e0 la surface du charbon, o\u00f9 leur activit\u00e9 catalytique d\u00e9clenche des r\u00e9actions d'hydrog\u00e9nation, d'oxydation et de synth\u00e8se. Le r\u00f4le du charbon est de retenir, d'activer et de stabiliser ces m\u00e9taux sans participer \u00e0 la r\u00e9action ni y interf\u00e9rer.<\/p>\n\n\n\n Le d\u00e9fi principal :<\/strong> Puret\u00e9 extr\u00eame, inertie et r\u00e9sistance m\u00e9canique.<\/p>\n\n\n\n M\u00eame la pr\u00e9sence de traces d'impuret\u00e9s m\u00e9talliques dans le carbone (fer, nickel, cuivre) peut alt\u00e9rer le catalyseur \u00e0 base de m\u00e9tal pr\u00e9cieux, ce qui r\u00e9duit son activit\u00e9 et raccourcit sa dur\u00e9e de vie. La chimie de surface doit \u00eatre ma\u00eetris\u00e9e afin d'\u00e9viter toute r\u00e9action secondaire ind\u00e9sirable. De plus, la r\u00e9sistance m\u00e9canique doit permettre de supporter les contraintes thermiques et chimiques li\u00e9es aux conditions de r\u00e9action.<\/p>\n\n\n\n Les grades de supports de catalyseurs de PureStar sont fabriqu\u00e9s pour normes de puret\u00e9 de qualit\u00e9 \u00e9lectronique, avec une teneur en m\u00e9taux contr\u00f4l\u00e9e et une composition chimique de surface neutre<\/strong>. Nos charbons en poudre de haute puret\u00e9, \u00e0 base de charbon et de sp\u00e9cialit\u00e9, offrent la surface sp\u00e9cifique et la r\u00e9partition des pores constantes n\u00e9cessaires \u00e0 une dispersion homog\u00e8ne du m\u00e9tal. Une documentation compl\u00e8te par lot r\u00e9pond aux exigences de qualification des fabricants de catalyseurs, garantissant ainsi que chaque lot respecte les m\u00eames crit\u00e8res de performance de r\u00e9f\u00e9rence.<\/p>\n\n\n\n Principaux avantages :<\/strong><\/p>\n\n\n\n <\/p>","protected":false},"excerpt":{"rendered":" Activated Carbon for Catalyst Support and Carrier Applications The structural foundation for advanced catalytic reactions.
