Effect of Demineralization Process on the CO2 Gasification of Lignite

Abstract

The effect of different demineralization process on CO₂ gasification of cokes obtained from Karaman / Ermenek lignite at different temperatures was investigated in this study. 10% and 20% hydrochloric acid (HCl), nitric acid (HNO₃) and sulfuric acid (H₂SO₄) 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 CO₂ at the temperatures ranging between 900°C–975°C were determined. The reaction capabilities of the demineralized lignite samples during CO₂ 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.
