Title (EN) MEANS AND PROCEDURE FOR GASIFICATION OF SOLID FUELS
(FR) MOYENS ET PROCEDE DE GAZEIFICATION DE CARBURANTS SOLIDES
Abstract: front page image
(EN)The process is using iron containing material for heat recovery and heat transfer in the pyrolysis and gasification stages. The iron containing material is simultaneously serving as a chemical reactant by reacting with supplied water or water vapor with formation of hydrogen. The process is carried out in three reaction steps: preheating (1) of the iron containing material, reduction (2) of the iron containing material with supplied solid fuel which is pyrolysed, and oxidation (3) of the iron containing material with water vapor simultaneously with gasification of eventually remaining pyrolysis residues from the reduction step (2) to a product gas containing varying quantities of hydrogen, carbon monoxide, methane, etc. The process has many fields of application from production of an intermediate Btu gas from urban waste to production of hydrogen from bio-fuels. The apparatus consists of several reactor parts with means (22) for transport of the iron containing material from the oxidation step (3) to the preheat step (1) and conduits (7) for transport of pyrolysis gas which remains from the reduction step (2) to the preheat step (1).
(FR)Le procede consiste a utiliser un materiau contenant du fer pour la recuperation et le transfert de chaleur lors des phases de pyrolyse et de gazeification. Le materiau contenant du fer sert simultanement de substance de reaction en reagissant avec de l"eau ou de la vapeur d"eau avec formation d"hydrogene le procede se deroule en trois phases reactionnelles: prechauffage (1) du materiau contenant du fer, reduction (2) du materiau contenant du fer avec du carburant solide qui est pyrolyse, et oxydation (3) du materiau avec de la vapeur d"eau simultanement a la gazeification d"eventuels residus de la pyrolyse provenant de la phase de reduction (2) en un produit gazeux contenant des quantites variables d"hydrogene, de monoxyde de carbone, de methane, etc. Le procede presente beaucoup de domaines d"application allant de la production d"un gaz intermediaire a partir des detritus urbains, a la production d"hydrogene a partir de bio-carburants. L"appareil comprend plusieurs parties de reaction avec des moyens de transport (22) du materiau contenant du fer de la phase d"oxydation (3) a la phase de prechauffage (1) et des conduites de transport du gaz de pyrolyse restant apres la phase de reduction (2) a la phase de prechauffage (1).
