(FR) CATALYSEUR D'EXTRACTION DE MATIÈRES VOLATILES POUR L'EXTRACTION DE MATIÈRES VOLATILES DE CHARBONS ET PROCÉDÉ POUR LA FABRICATION DE COKE PRÉSENTANT DES VALEURS DE CRI ET DE CSR AMÉLIORÉES UTILISANT UN TEL CATALYSEUR
Abstract
(EN)
A devolatalisation catalyst for devolatalisation of coals comprising at least one of copper oxide and manganese oxide and a process for producing coke with improved CRI and CSR is disclosed by faster carbonization of coal blend in presence of said catalyst. More particularly, a cost effective process is proposed enabling use of inferior quality coal(non-coking coal) and reduced quantity of costly and scarce hard coke, by stamping of coal blend in multiple layers to desired bulk density with a uniform layer of a combination of two different chemicals mixed in a preferred ratio as catalyst, on each layer of coal blend subjected to carbonization. The catalytic devolatalization of coal blend drives out the volatile components much early when the coal blend is highly fluid, thus producing hard and less porous coke with (lesser CRI & higher CSR) CRI improved by 1.0-3.0% and CSR improved by 1.5-4% and reduced the carbonization completion time improving productivity by about 3%.

L'invention porte sur un catalyseur d'extraction de matières volatiles pour l'extraction de matières volatiles de charbons, comprenant au moins l'un de l'oxyde de cuivre et de l'oxyde de manganèse, et sur un procédé pour la production de coke présentant un CRI et un CSR améliorés, par une carbonisation plus rapide de mélange de charbons en présence dudit catalyseur. Plus précisément, l'invention porte sur un procédé économiquement rentable permettant l'utilisation de charbon de qualité inférieure (charbon non cokéfiant) et d'une quantité réduite de coke métallurgique onéreux et rare, par pressage de mélange de charbons en couches multiples à une masse volumique apparente souhaitée avec une couche uniforme d'une association de deux produits chimiques différents mélangés en un rapport préféré utilisée comme catalyseur, sur chaque couche de mélange de charbons soumis à une carbonisation. L'extraction catalytique de matières volatiles du mélange de charbons entraîne les composants volatils vers l'extérieur plus tôt lorsque le mélange de charbons est hautement fluide, ce qui produit ainsi du coke métallurgique et moins poreux présentant un CRI amélioré (inférieur) de 1,0-3,0 % et un CSR amélioré (supérieur) de 1,5-4 % et réduit le temps pour arriver à une carbonisation complète, ce qui améliore la productivité d'environ 3 %.
