This article investigates the possibility of using trona minerals in the oxydesulfurization of coal. The experiments were performed on a Turkish lignite having high organic and high pyritic sulfur content from the Gediz area. Oxydesulfurization of the lignite sample using trona minerals was studied at 423--473 K, under 0--1 MPa oxygen partial pressure at 0--0.3 M equivalent alkalinity of Na{sub 2}CO{sub 3} for 2.5--60 min. Almost all of the pyritic sulfur content and, depending on the working conditions, an important part of the organic sulfur content were removed. Unless the temperature reached 473 K, solid product yield was not negatively affected. Trona minerals were seen as a suitable alkaline to use in oxydesulfurization of coal.
