TL;DR: In this article, the water-gas shift reaction was applied to the upgrading of three samples of naturally weathered inert-rich coal from Western Canada demonstrating the transformation from non-coking to coking coal.

TL;DR: In this article, the Disclosure Combination method for the gasification of coal and the reduction of metal ores involving hydrogenation of coal to produce hydro-carbons and coke component is described.
Abstract: of the Disclosure Combination method for the gasification of coal and the reduction of metal ores involving hydrogenation gasification of coal to produce hydro-carbons and coke component. The coke is subjected to steam gasification and the gas therefrom used to reduce ores. Spent gas from the reduction is treat-ed to convert CO in the gas to H2 and CO2. The CO2 is scrubbed out and the H2 is sent to the hydrogenation gasification to hydrogenate the coal.

TL;DR: Capillary gas chromatography has been used for characterizing naphtha produced from coprocessing coal and heavy oil at various conditions as mentioned in this paper, and the combined use of hydrogen sulphide and iron sulphate as promoter resulted in higher contents of indan, alkanes and cycloparaffins than the use of either alone.

TL;DR: A low-temperature, coal-extraction technique utilizing the solvent N-methyl-2-pyrrolidone has been shown to enhance significantly the rate of gasification of the residual, unextracted portion of the coal as compared to that of the raw coal as mentioned in this paper.
Abstract: A low-temperature, coal-extraction technique utilizing the solvent N-methyl-2-pyrrolidone has been shown to enhance significantly the rate of gasification of the residual, unextracted portion of the coal as compared to that of the ray coal. Five coal/residue pairs were subjected to gasification in a carbon dioxide atmosphere at temperatures of 1200-1500'K and atmospheric pressure. In all cases, the activation energy (as described by an Arrhenius-type relationship) of the residue was found to be lower than that of the raw coal. In addition, over the temperature range studied, the residues exhibited rate constants as much as four times larger than those for the raw coals. A trend vas found to exist between the extent of extraction and the ratio of the activation energies of the residue and raw coal. It is postulated that this behavior is a manifestation of a complex combination of catalytic and surface area effects. The technique of solvent extraction followed by gasification of the residue may con...
