Title
(EN) PELLETIZED ACTIVATED CARBON AND METHODS OF PRODUCTION
(FR) CHARBON ACTIF MIS EN PASTILLES ET PROCÉDÉS D'UTILISATION
Abstract
(EN)
Activated carbon for removal of sulfur containing materials from fluids. The activated carbon has a high sulfur capacity and can be manufactured without the addition of a catalyst. Lignite is treated to provide an activated carbon with a high mesoporosity and total surface area. The starting material has a high ash content, such as greater than 10% by weight.
(FR)
La présente invention concerne du charbon actif pour l'élimination de matériaux qui contiennent du soufre à partir de fluides. Le charbon actif a une haute capacité au soufre et peut être fabriqué sans ajout de catalyseur. Le lignite est traité pour fournir un charbon actif avec une mésoporosité et une superficie totale. Le matériau de départ a une haute teneur en cendres, par exemple de plus de 10 % en poids.
