Abstract :The effect of different demineralization process on CO 2 gasification of cokes obtained from Karaman / Ermenek lignite at different temperatures was investigated in this study. 10% and 20% hydrochloric acid insert ignore into journalissuearticles values(HCl);, nitric acid insert ignore into journalissuearticles values(HNO 3 ); and sulfuric acid insert ignore into journalissuearticles values(H 2 SO 4 ); solutions were used in the demineralization process. The demineralized lignite samples were subjected to coking process at the temperatures ranging between 500°C-800°C, and the reaction capabilities of the obtained cokes in the gasification reaction with CO 2 at the temperatures ranging between 900°C–975°C were determined. The reaction capabilities of the demineralized lignite samples during CO 2 gasification were observed to be lower than those of the samples untreated with acid. In addition, it was observed that the reaction capabilities of cokes increased with increasing of coking temperature.
