En g\u00e9n\u00e9ral, on suit la r\u00e8gle du 2X (ou gradation), c'est-\u00e0-dire que le diam\u00e8tre du catalyseur est de 1,5 cm. <a href=\"https:\/\/www.aluminaceramicball.com\/fr\/defauts-courants-et-analyse-des-causes-des-billes-en-ceramique-a-haute-teneur-en-alumine\/\">bille en c\u00e9ramique<\/a> doit \u00eatre deux fois plus grand que le diam\u00e8tre du catalyseur adjacent afin que la distribution des mat\u00e9riaux soit la plus uniforme possible, que la chute de pression soit la plus faible possible et que le r\u00e9acteur soit optimis\u00e9.<\/p>\n<p>Dans un r\u00e9acteur \u00e0 lit fixe, une certaine hauteur de <a href=\"https:\/\/www.aluminaceramicball.com\/fr\/produit\/billes-ceramiques-inertes-en-alumine\/\">billes c\u00e9ramiques inertes<\/a> ou des charges sont g\u00e9n\u00e9ralement ajout\u00e9s au-dessus et au-dessous du catalyseur.<\/p>\n<p>La fonction de la bille en c\u00e9ramique sup\u00e9rieure est mieux comprise et am\u00e9liore la distribution de l'alimentation. Quel est le r\u00f4le de la bille c\u00e9ramique inf\u00e9rieure ? S'agit-il simplement d'un support de catalyseur ? Est-il possible de le faire ?<\/p>\n<p>En outre, il existe des r\u00e8gles strictes concernant la hauteur de remplissage des billes c\u00e9ramiques inertes. Quelle est la base de cette hauteur r\u00e9glementaire ?<\/p>\n<p>En g\u00e9n\u00e9ral, deux couches sont pos\u00e9es. La couche proche du catalyseur est recouverte de billes de porcelaine de 1 \u00e0 3 mm, la couche ext\u00e9rieure est recouverte de billes de porcelaine de 4 \u00e0 6 mm et le treillis m\u00e9tallique est pos\u00e9 sur la couche la plus externe. Le treillis m\u00e9tallique est principalement utilis\u00e9 pour la distribution des gaz, le filtrage des petites particules de catalyseur entra\u00een\u00e9es par le gaz ou le filtrage des impuret\u00e9s qui p\u00e9n\u00e8trent dans le lit. Il joue \u00e9galement un r\u00f4le dans la pr\u00e9vention de la chute du lit et le soutien du lit. En g\u00e9n\u00e9ral, chaque taille de bille en c\u00e9ramique a une \u00e9paisseur de 100 mm. Je n'ai pas remarqu\u00e9 que cette norme contenait des r\u00e8gles. M\u00eame les particules de catalyseur tr\u00e8s fines ne peuvent pas \u00eatre filtr\u00e9es par cette m\u00e9thode, et d'autres m\u00e9thodes doivent \u00eatre utilis\u00e9es pour filtrer le catalyseur.<\/p>","protected":false},"excerpt":{"rendered":"<p>The size of the inert ceramic ball should be selected according to the size of the catalyst.
