Title (EN) DESULFURIZATION OF CARBONACEOUS MATERIALS
(FR) DESULFURATION DE MATERIAUX CHARBONNEUX
Abstract: front page image
(EN)Solid carbonaceous material, especially coal or coal char, is desulfurized by treatment with a limited amount of hydrogen to convert the organic sulfur to sulfide sulfur at an elevated temperature. The thusly formed sulfide sulfur is then removed from the solid carbonaceous material by steam treatment or other means.
