Liquefaction of Morwell brown coal using synthesis gas and hydrogenated anthracene oil
TLDR
In this article, the effect of synthesis gas as a potential reductant for a brown coal (Morwell) was compared with pure hydrogen and pure carbon monoxide using hydrogenated anthracene oil as solvent and a catalyst comprising 3% iron ore and 1% sulphur.About:

Industrial implications of the properties of brown coals
D.J. Allardice,B.S. Newell +1 more
TL;DR: In this article, the authors provide an overview of the industrial implications of the properties of brown coal, including drying and briquetting processes, which are also usually prerequisites for the carbonization and gasification of soft brown coals such as those found in Victoria.

Hydrogenation and reduction
W. Roy Jackson,Frank P. Larkins +1 more
TL;DR: In this article, the chemical and physical processes involved in the conversion (reduction) of brown coals to liquid products with particular regard to the effects of coal characteristics (organic structure and inorganic material present); the role of the slurring solvent; the pyrolytic decomposition of the coal; the nature and role of catalysts or promoters in hydrogen transfer reactions between hydrogen gas and donor solvents and/or direct transfer to coal; and the yield and nature of the primary liquid products.

Preliminary investigations on the catalytic hydrogenation of polycyclic aromatic hydrocarbons via WGSR
TL;DR: In this paper, a polycyclic aromatic hydrocarbon in coal (anthracene) undergoes partial cracking and polycondensation under non-hydrogen-donor conditions at 400°C, which provides theoretical support for catalytic hydrogenation in direct liquefaction of lignite in a syngas (CO+H2) system.

Yoshihisa Watanabe,Hiroaki Yamada,Nori-aki Kawasaki,Kenji Wada,Kazu-aki Hata,Take-aki Mitsudo +5 more
TL;DR: Pentacarbonyliron with sulfur was found to be an excellent catalyst precursor for liquefaction of Yallourn coal using syngas-water as a hydrogen source as mentioned in this paper.

Free radical chemistry of coal liquefaction: role of molecular hydrogen
TL;DR: In this article, the authors showed that molecular hydrogen can participate directly in free radical reactions under coal liquefaction conditions, and that the rate of the reaction is directly proportional to the hydrogen pressure.

Mechanisms leading to process improvements in lignite liquefaction using CO and H2S
TL;DR: In this paper, a review of the role of carbon dioxide and hydrogen sulphide in lignite liquefaction is presented, with a focus on the importance of catalytic amounts of H 2 S as a homogeneous catalyst.
Coal liquefaction with synthesis gas
TL;DR: In this article, a variety of coals were converted in batch autoclaves to a low-sulfur fuel oil at temperature of 425 to 450/sup 0/C and pressures of 2200 to 2400 psig, using 1:1 (H/sub 2/:CO) synthesis gas at reaction times of 30 to 60 minutes at temperature.
