The role of sulphur in coal hydroliquefaction
Martin J. Trewhella,Alan Grint +1 more
TL;DR: In this paper, the effects on coal hydroliquefaction of organic and pyritic sulphur, and of H 2 S formed from the reductive decomposition of these compounds, are reviewed.

Iron(II) Disulfides as Precursors of Highly Selective Catalysts for Hydrodeoxygenation of Dibenzyl Ether into Toluene
TL;DR: In this paper, it was shown that nanocrystalline pyrite and marcasite (FeS2) are precursors of highly active catalysts for the hydrodeoxygenation of dibenzyl ether into toluene.

Suppression of Addition Reactions during Thermal Cracking Using Hydrogen and Sulfided Iron Catalyst
TL;DR: In this paper, a model compound was used to probe cracking and addition reactions in the liquid phase of bitumen and showed that addition reactions can be suppressed under hydrogenation conditions by using iron sulfide as a low-activity catalyst in the presence of hydrogen gas and a hydrogen donor solvent.
Journal ArticleDOI
Catalytic activity of various iron sulphides in coal liquefaction
TL;DR: In this article, the authors compared the catalytic activity of pyrite, troilite, and iron(III) sulfide for coal liquefaction and found that pyritic acid is converted to pyrrhotite before the onset of exothermic reactions from coal hydrogenolysis.

Xiangxian Ma,Jianjing Zheng,Guodong Zheng,Wang Xu,Yu Qian,Yanqing Xia,Zuodong Wang,Xiaofeng Wang,Xiyan Ye +8 more
TL;DR: In this article, a coal sample containing type-III kerogen was selected from the Junggar Basin and investigated for gas generation using anhydrous pyrolysis either or not added pyrite at 250°C, 300 ¼C, 350 ¼c, and 400 ¼ c for 72h each.

Hydrogenation of Coal and Tar
W. R. K. Wu,H. H. Storch +1 more
TL;DR: In this article, the development of high pressure coal and tar hydrogenation technology, based on an intensive review of the pertinent literature, is described, and the history and economics of the process, chemical aspect of hydrogenation of coal, tar, and middle oil, the engineer aspect of converting coal andtar to liquid fuels, principally gasoline, and equipment for the process.

Mössbäuer study of decomposition of pyrite in hydrogen
TL;DR: In this paper, the decomposition of coal and mineral pyrite in a hydrogen atmosphere is dependent on particle size, and a significant reduction in the activation energy as a function of the particle size was also observed.
