In this paper, a novel type of composite inhibitor (PAA/SA-CC) was developed and characterized with the aim of achieving sustained and highly effective inhibition on spontaneous combustion of low-rank coal. A concept of realizing the caged-wrapping and sustained-releasing function of polymer as regard to high-activity chemical inhibitor was proposed, basing on which the composite inhibitor was prepared...
We have developed a new class of aqueous Pickering foams, which were stabilized by sodium dodecyl sulfate (SDS)-modified micro fly ash (FA) particles and exhibited excellent stability and inhibition characteristics for coal spontaneous combustion. Specifically, this study aimed to characterize the microstructure, foaming behavior, evolution process and inhibition characteristic for coal spontaneous...
Because of the complex structure of coal, selecting an efficient chemical inhibitor to retard or prevent its spontaneous combustion remains a challenging task. In the present work, the distributions and concentrations of functional groups on coal surfaces were analyzed using in situ FTIR. The active functional groups and their oxidation processes were elucidated so as to develop an efficient approach...
