Low-Temperature Oxidation Gas Products and Spontaneous Combustion Tendency of Shengli Lignite

Abstract:

Oxygen adsorption and CO₂ produced of samples at different adsorption temperatures was investigated, Combined with thermal analysis method, the combustion properties of coal samples was determined. The results show that the oxygen adsorption capacity and CO₂ produced of the samples increase and later decrease with the enhanced of pyrolysis degree. In the process of low-temperature oxidation, coal molecular side chains break, then H₂O, CO, CO₂ and so on are detected in turn; with the enhanced of pyrolysis degree, it reveals that combustion reaction activity decreased and spontaneous combustion tendency weakened.
