Are Ionic Liquids Suitable for Suppressing Coal Spontaneous Combustion?

Modelling Spontaneous Combustion of Coal

Spontaneous combustion of coal is an important problem in mining and storage, in terms of both safety and economics. This is because coal reacts with oxygen in the air and an exothermic reaction occurs, even in ambient conditions. The heat of the reaction accumulates and the reaction becomes progressively faster and thermal runaway may take place to the point of ignition. A detailed computer mo...

Systems Analysis of Ionic Liquids for Post-combustion CO2 Capture at Coal-fired Power Plants

The main objective of this study is to investigate the feasibility and costs of ionic liquid (IL)-based CO2 capture systems at pulverized coal-fired (PC) power plants. The IL selected for this assessment is trihexyl(tetradecyl)phosphonium 2-cyanopyrrolide ([P66614][2-CNpyr]), achieving a 1:1 and reversible chemical reaction between [2-CNpyr] and CO2. A multi-stage equilibrium-based modeling fra...

High-throughput approach for the identification of anilinium-based ionic liquids that are suitable for electropolymerisation.

We report the synthesis of new protic ionic liquids (PILs) based on aniline derivatives and the use of high-throughput (HT) techniques to screen possible candidates. In this work, a simple HT method was applied to rapidly screen different aniline derivatives against different acids in order to identify possible combinations that produce PILs. This was followed by repeating the HT process with a...

Coal Combustion and Combustion Products

Applying rock engineering systems (RES) approach to evaluate and classify the coal spontaneous combustion potential in Eastern Alborz coal mines

Subject analysis of the potential of spontaneous combustion in coal layers with analytical and numerical methods has been always considered as a difficult task because of the complexity of the coal behavior and the number of factors influencing it. Empirical methods, due to accounting for certain and specific factors, have not accuracy and efficiency for all positions. The Rock Engineering Syst...
