Coal spontaneous combustion (CSC) is an extremely complex physical and chemical reaction between coal and oxygen, and it results in the gradual accumulation of thermal energy that eventually produces conditions that are favorable for combustion. Ionic liquids (ILs) inhibit coal oxidation and reduce the amount of heat that is produced. A synchronous thermal analyzer was used to examine the effects of imidazolium-based ILs on bituminous coal from two sources. The results revealed that with the… 
Thermal effect of ionic liquids on coal spontaneous combustion
Coal spontaneous combustion (CSC) is a global, long-standing thermal hazard in coal mining that causes serious environmental damage, particularly in developing countries. Ionic liquids (ILs) are
Effects of 1-butyl-3-methylimidazolium tetrafluoroborate and the oxygen concentration on the spontaneous combustion of coal
Ionic liquids (ILs) are a type of environmentally friendly solvents. Several studies have proven that ILs can inhibit the spontaneous combustion of coal (SCC). In this study, a synchronous thermal
Effect of Water Evaporation on the Inhibition of Spontaneous Coal Combustion
Spontaneous coal combustion is the primary cause of coal mine fires. During the production process, spontaneous coal combustion in the goaf is often affected by air leakage, which weakens or annuls
Inhibition of coal spontaneous combustion by an environment-friendly, water-based fire extinguishing agent
At present, inhibitors have been widely used in the field of coal fire prevention and control, but there are some defects in the use of them. So it is necessary to find a new practical and economical
Effects of ionic liquid concentration on coal low‐temperature oxidation
In order to find out the optimal concentration of ionic liquid to lower the cost of inhibiting coal spontaneous combustion, effects of aliphatic hydrocarbons, hydrogen bonds, and some structural
Inhibition performance of microcapsule material on coal oxidation
The frequent occurrence of coal spontaneous combustion (CSC) poses a serious threat to coal mine production safety. Inhibitor fire extinguishing technology has therefore played an important role in
Experimental and theoretical study on kinetic behaviour of coal gangue and raw coal using model reconstruction
Coal gangue (CG) and raw coal (RC) can catch fire due to spontaneous combustion. The combustion characteristics, functional groups, and kinetic behaviour of CG and RC were investigated to assess


Effects on the activities of coal microstructure and oxidation treated by imidazolium-based ionic liquids
To study the effect of ionic liquids (ILs) of the microstructure on the surface of the coal, four ILs ([Emim][BF4], [Bmim][BF4], [Bmim][NO3], and [Bmim][I]) were selected to treat the coal samples.
Investigations into physicochemical changes in thermal coals during low-temperature ionic liquid treatment
Two Australian thermal coals were treated with four different ionic liquids (ILs) at temperatures as low as 100 °C. The ILs used were 1-butylpyridinium chloride ([Bpyd][Cl]),
Thermal hazard analysis and combustion characteristics of four imidazolium nitrate ionic liquids
Thermogravimetry and differential scanning calorimetry (DSC) were used to investigate the thermal stability of four nitrate-based ionic liquids. The variations of thermal behavior for different
Dissolution and Dispersion of Coal in Ionic Liquids
In “good” solvents such as pyridine, coal particles swell and fracture to some degree as soluble material is extracted, but they remain as more-or-less coherent particles. It is shown here that
