Abstract

La présente invention concerne un procédé pour traiter des déchets organiques fibreux (EFB, Empty Fruit Bunches ou rafles), de telle sorte que les EFB puissent être utilisés dans des gazéifieurs à lit fixe afin de produire des produits gazeux (gaz de bois). L'invention concerne en outre un procédé pour mettre en œuvre un gazéifieur à lit fixe afin de produire un produit gazeux à partir de déchets organiques fibreux (EFB) traités de cette manière. Non traités, ces déchets organiques fibreux en tant que combustible présentent de mauvaises propriétés en termes de teneur en cendres et de point de fusion des cendres. Pour élever le point de fusion, un procédé de lixiviation a été développé, dans lequel des EFB broyés sont plongés dans de l'eau de mer chauffée pendant un certain temps en ajoutant de la chaux vive, du calcaire et/ou du kaolin. Cette lixiviation vise à réduire les constituants des cendres critiques à bas point de fusion dans les EFB, de manière à améliorer leurs propriétés de combustion. En utilisant de l'eau de mer au lieu de l'eau potable ou de l'eau distillée, le procédé est particulièrement écologique et économique. Après séchage, il résulte un combustible pour gazéifieurs à lit fixe qui ne fond plus à une température de 1100 °C et qui présente une teneur en cendres inférieure à 10 % en poids.
