Abstract Acid treatment changes the evolution of coal microstructure, and exploring the internal relationship between different acid treatment and coal oxidation is of great significance for the prevention of coal spontaneous combustion. In this paper, lignite collected from Ximeng mine was treated with hydrochloric acid and nitric acid. The oxidation performance and microstructure parameters of treated coal were analyzed by gas chromatograph, mercury intrusion, FTIR and XPS. According to test results, low-temperature (T
