Title
(EN) REACTOR AND PROCESS FOR GASIFYING AND/OR MELTING OF FEED MATERIALS
(FR) RÉACTEUR ET PROCÉDÉ DE GAZÉIFICATION ET/OU DE FUSION DE MATÉRIAUX DE CHARGE
Abstract
(EN)
This invention relates to a method and a reactor for gasifying a carbonaceous feedstock material. The method includes the steps of choke-feeding a carbonaceous feedstock material into a pyrolysis zone of the reactor to form a discharge bed; heating the discharge bed to initiate pyrolysis of the feedstock material to form a pyrolysis product; providing a lower lying upper oxidation zone; gasifying the pyrolysis product to form a bed of char; converting thermal energy into chemical energy in an upper reduction zone; providing a lower lying lower oxidation zone; collecting any metal slag and/or slag melts in the lower oxidation zone; and discharging hot reducing gases having a temperature of at least 1300°C and a CO/CO2 ratio of ≥ 5, more preferably ≥ 15.
(FR)
La présente invention concerne un procédé et un réacteur pour gazéifier une matière première carbonée. Le procédé comprend les étapes consistant à alimenter par étranglement une matière première carbonée dans une zone de pyrolyse du réacteur pour former un lit de décharge ; chauffer le lit de décharge pour initier la pyrolyse de la matière première pour former un produit de pyrolyse ; fournir une zone d'oxydation supérieure basse ; gazéifier le produit de pyrolyse pour former un lit de produit de carbonisation ; convertir l'énergie thermique en énergie chimique dans une zone de réduction supérieure ; fournir une zone d'oxydation inférieure basse ; collecter des scories et/ou des scories métalliques fondues dans la zone d'oxydation inférieure ; et évacuer les gaz réducteurs chauds ayant une température d'au moins 1300 °C et un rapport CO/CO2 ≥ 5, de préférence ≥ 15.
