Title (EN) ACTIVE COKE PRODUCED FROM PIT COAL AND PRODUCTION PROCESS THEREOF
(FR) COKE ACTIF FABRIQUE A PARTIR DE HOUILLE ET SON PROCEDE DE FABRICATION
Abstract:
(EN) The granulates of active coke produced from pit coal have an inactive abrasion-proof core based on coal or a ceramic material, as well as an envelope based on active coke particles adhering to the core. Various processes for producing said granulates are disclosed. In one embodiment, a ground coal covering is applied to the core before activation; another embodiment provides for the application of a covering based on coke particles already activated. In a third embodiment, on the inactive core based on swollen and burned material there is first provided an intermediary layer based on a material which volatilizes partly during the carbonizing treatment in order to compensate for the expansion differences of the core and of the envelope.
(FR) Les granulats de coke actif fabriqué à partir de houille possèdent un noyau inactif résistant à l'abrasion à base de charbon ou d'une matière céramique, ainsi qu'une enveloppe à base de particules de coke actif adhérant au noyau. Différents procédés de fabrication de ces granulats sont décrits. Dans un mode de réalisation, une enveloppe de houille broyée est appliquée sur le noyau, avant l'activation; un autre mode de réalisation prévoit l'application d'une enveloppe à base de particules de coke déjà activées. Dans un troisième mode de réalisation, sur le noyau inactif à base de matériau gonflé et brûlé est prévue tout d'abord une couche intermédiaire à base d'une matière se volatilisant en partie lors du traitement de carbonisation, afin de compenser les différences de dilatation du noyau et de l'enveloppe.
