TL;DR: In this article, the characteristics of structure and pyrolysis behavior of fine gasification ashes and raw coals with different coal gasification technologies were studied by proximate analysis, ultimate analysis, FTIR and TG-MS.
Abstract: Raw coals as well as fine gasification ashes from pulverized coal gasifier and coal water slurry (CWS) gasifier were studied by proximate analysis, ultimate analysis, FTIR and TG-MS to determine the characteristics of structure and pyrolysis behavior of fine gasification ashes and raw coals with different coal gasification technologies Some volatile matter remained in fine gasification ash after coal gasification, and the volatile matter content of ash was related to the gasification technology During gasification, part of the functional groups kept undecomposed and rearrangement of molecular structures caused formation of some relatively stable functional groups, such as phenolic aldehyde, carbonate minerals and oxy-compound structures

TL;DR: In this article, the fusibility of coal ash has become of considerable value to the consumer of coals, mainly in connection with the troublesome formation of clinker from the melting of the ash constituents of the burning coal.
Abstract: From Introduction: "Information concerning the fusibility of coal ash has become of considerable value to the consumer of coals, mainly in connection with the troublesome formation of clinker from the melting of the ash constituents of the burning coal. It is hoped that this information when used together with the large number of coal analyses published by the bureau will assist the consumer of coal in comparing different coals, and in selecting the coal best adapted for his purpose."

TL;DR: The structural index of coals δ, which characterizes the degree of unsaturation of organic matter, was used for predicting the degrees of conversion of brown and black coals from the promising deposits of Mongolia in the process of hydrogenation as discussed by the authors.
Abstract: The structural index of coals δ, which characterizes the degree of unsaturation of organic matter, was used for predicting the degrees of conversion of brown and black coals from the promising deposits of Mongolia in the process of hydrogenation. The results of experimental studies on the hydrogenation of the most suitable coals chosen on this basis (from the Talbulag and Bayanteg deposits) for the manufacture of liquid products are given.
