Abstract:
(EN) The invention relates to a novel multi-tube system for the gas-phase synthesis of carbon nanotubes. The purpose of the invention is to design a production-maximising system for the production of high-purity nanotubes, involving one-step gas-phase synthesis. The invention comprises a reaction system which is introduced into a horizontal oven which is supplied with the mixture of reactives and inerts and which is equipped with an outlet for vaporised gases. The reaction system is equipped internally with the multitube reactor comprising a tube which has a smaller diameter than that of the reactor and which, in turn, contains a variable number of hollow tubes. The length of the multitube reactor is selected such that it is within the stable operating temperature area of the oven.
(ES) El objetivo de la presente invención es diseñar un sistema, maximizando la producción, para la fabricación de nanotubos de alta pureza mediante la síntesis en fase gas en un solo paso. Consiste en un sistema de reacción, introducido en un horno horizontal, que se alimenta con la mezcla de reactivos e inertes y, el cual tiene una salida de los gases vaporizados. Dentro del sistema de reacción se halla el reactor multitubular compuesto por un tubo de diámetro inferior al del reactor, el cual a su vez contiene un número variable de tubos huecos. La longitud del reactor multitubular se escoge de tal forma que esté dentro de la zona estable de temperatura de trabajo del horno.
(FR) L'objectif de cette invention consiste à concevoir un système destiné à la fabrication de nanotubes de haute pureté par le biais de la synthèse en phase gazeuse en une seule étape en réduisant au maximum la production. Cette invention consiste en un système de réaction, introduit dans un four horizontal qui s'alimente avec le mélange de réactifs et de produits inertes et, possédant une sortie des gaz vaporisés. Dans les systèmes de réaction se trouve le réacteur multitubulaire composé d'un tube de diamètre inférieur à celui du réacteur, lequel à son tour contient un nombre variable de tubes creux. La longueur du réacteur multitubulaire est choisie de manière à se trouver dans la zone stable de température de travail du four.
