Gareth D. Mitchell, in Applied Coal Petrology, Process and Methods for Coal Liquefaction. Coal liquefaction technology began in Germany when Frederick Bergius showed that it was possible to add hydrogen to coal at –°C and MPa to produce distillate products (Bergius, ). During the period of –, the process was refined and I. G. . Liquefaction can be direct, from the coal itself, or indirect, from synthesis gas (CO and H2) obtained by gasification of the coal. Coal liquefaction incorporates both an increase in . Abstract. We divide coal liquefaction processes into four categories: (1) indirect liquefaction, such as Fischer-Tropsch and methanol synthesis, in which coal is fist gasified to produce a synthesis gas which is then recombined to produce liquids; (2) direct liquefaction processes, typified by H-Coal, Exxon Donor Solvent (EDS), and SRC-I and II, in which a slurry of coal and solvent is.   Abstract The article contains sections titled: 1. Introduction Commercial Development Historical Background 2. Indirect Coal Liquefaction Preparation of Synthesis Gas Coal Gas.

Coal Liquefaction Definition. The process of coal liquefaction creates synthetic liquid fuels from solid coal as substitutes for various petroleum products. There are two types of liquefaction - direct and indirect Williams R. H., Larson, E. D. (December ). A comparison of direct and indirect liquefaction technologies . Details. The processes are used for scientific, industrial and commercial purposes. Many gases can be put into a liquid state at normal atmospheric pressure by simple cooling; a few, such as carbon dioxide, require pressurization as well. Liquefaction is used for analyzing the fundamental properties of gas molecules (intermolecular forces), or for the storage of gases, for example: . The book treats the conversion of coal into liquids in terms of the structural and functional differences between the coal and the desired products, with particular emphasis on thermal processes for coal liquefaction. The chemical and structural composition of coal and the liquids to be derived from coal are reviewed, and the significance of the physical properties and rank of Cited by:

  The actions of hydrogen, molecular oxygen and oxidising agents on coal are updated and a newly written chapter treats the grand processes of coal conversion (combustion, gasification, carbonisation and liquefaction). Coal constitution in its diverse aspects is revised with a practically complete survey of many proposed coal Edition: 3. Abstract. The ASPEN process simulator has been used to model an indirect-liquefaction flowsheet patterned after that of the Tri-State project. This flowsheet uses Lurgi moving-bed gasification with synthesis-gas conversion to methanol folowed by further processing to gasoline using the Mobil MTG process. Coal liquefaction incorporates both an increase in the H/C ratio and removal of heteroatoms (S, N, O) and inorganic oxides (ash). Successful industrial processes must incorporate both these steps.
