TL;DR: In this paper, pertrifluoroacetic acid (CF3COOH) was used for coal structure determination and the results showed that the method could not be easily applied to structure determination.

TL;DR: In this paper, a thermodynamic approach to the description of the behavior of the system fuel-oxidizer in oxygen gasification of coal is used to reveal the main mechanisms of the process of capture of sulfur by the mineral part of the coal.
Abstract: A thermodynamic approach to the description of the behavior of the system fuel-oxidizer in oxygen gasification of coal is used to reveal the main mechanisms of the process of capture of sulfur by the mineral part of the coal and to determine the fundamental possibility of the process for coals from different coal fields

TL;DR: In this paper, the authors present a concept of the integration of coal liquefaction with "regular" type electrode coke production, and the characteristics of the parent coal, the heavy product of hydrogenation and its fractions as well as the physicochemical and textural properties of the carbonization product of heavy hydrogenated oil and its fraction are discussed.

TL;DR: In this article, coal was extracted with octene-1, decene-2, dodecene-3, tetradecene-4, and cetene-5 at their boiling points and the residual coal obtained was further extractable in quinoline up to 39% extent.
Abstract: Assam coal has been extracted with octene-1, decene-1. dodecene-1, tetradecene-1 and cetene-1 respectively-at. their boiling points. More than 50% coal was extracted using cetene-1 as a solvent and the residual coal obtained was rendered further extractable in quinoline up to 39% extent. Thus, more than 707% coal was rendered extractable in cetene-1 followed by quinoline extraction. This was more than that observed through the successive extractions in anthracene as followed by quinoline extraction (60%). These studies showed alkenes to be very promising for the extraction of coal for industrial operations, as these are coal and petroleum derived solvents.

TL;DR: In this paper, a simple model has been developed to predict the diffusion-limited accumulation of Fe and Ti in coal liquefaction catalysts used in the Wilsonville, AL, two-stage liquidation (TSL) pilot plant.
Abstract: A simple model has been developed to predict the diffusion-limited accumulation of Fe and Ti in coal liquefaction catalysts used in the Wilsonville, AL, two-stage liquefaction (TSL) pilot plant. The model has the form of two ordinary differential equations (ODE's) which can be solved by using a simple finite difference scheme with time stepping. The model is based on a first-order adsorption of contaminant with linear site blocking and subsequent saturation. The Thiele moduli for both contamination processes have been estimated to be in the range 3 - 7. This model was developed after an extensive characterization of fouled catalysts was combined with a series of numerical experiments based on a more general partial differential equation model which included transient behavior and various adsorption and site blocking orders. The results of the model discrimination demonstrate the advantages of using data such as the spatial distribution of contaminants in the process of model development.
