TL;DR: In this article, the kinetic behavior of 22 brown coals was investigated in direct hydroliquefaction and the computer simulation of the hydrogenation kinetics was used to calculate rate constants.

TL;DR: In this paper, coal asphaltenes derived from the Catalytic Incorporated coal liquefaction process were oxidized by two methods; 1) heat treatment in air at high temperature for several hours and 2) oxidation over chromyl chloride using the Law and Perkin method.

TL;DR: In this paper, the authors examined the catalytic properties of various iron ores, such as hematite, limonite and magnetite, mixed with sulfur in order to develop a disposable catalyst in direct liquefaction of coal.
Abstract: Catalytic activities of various iron ores, hematite, limonite and magnetite, mixed with sulfur were examined in order to develop a disposable catalyst in direct liquefaction of coal. The catalytic mechanism was investigated with differential thermal analysis and X-ray diffraction analysis. The following results were obtained: Most of the iron ores mixed with sulfur were as active as or more active than red mud mixed with sulfur, which has been regarded as a catalyst, even under relatively mild liquefaction conditions. The resulting liquefaction products were rich in middle and light oils. Thus, they are expected to become one of the catalysts; the catalytic mechanism in the presence of these iron ores plus sulfur, except for magnetite, was found to be similar to that of Fe/sub 2/O/sub 3/ mixed with sulfur.

TL;DR: In this paper, the main technical and structural characteristics of Tavantolgoi coal from Mongolia are determined and the type, code number and other valuable technological indexes of the coal are estimated according to the international classification system of coals.
Abstract: Main technical and structural characteristics of Tavantolgoi coal from Mongolia are determined. Type, code number and other valuable technological indexes of the coal are estimated according to the international classification system of coals. Cokes obtained in a laboratory chamber stove and in a reactor was characterized.
