A description is presented of the general criteria for the selection of materials for coal liquefaction catalysis. In addition to their catalytical effectiveness prospective catalysts must be able to meet certain criteria regarding their thermal and chemical stability. By comparing free energies of formation, it is possible to make a qualitative evaluation of the relative stability of various
Potential second-generation catalytic materials for the direct liquefaction of coal to boiler fuel are studied. Both fundamental aspects and engineering constraints were considered in evaluating materials and assigning a priority for further study. A synopsis of relevant background information, the nature of the study, and the evaluation of materials is presented along with a detailed

OSTI.GOV Technical Report: (Coal liquefaction and materials) (Coal liquefaction and materials) Full Record; Other Related Research
The corrosion response of alloys in various process environments in coal liquefaction pilot plants is discussed. Causes of corrosion and limiting conditions (such as temperature, pressure, and fluid velocity) are addressed. Solutions and needed development are emphasized.
2017-1-16 2017-1-16 Coal liquefaction is an industrial process in which coal as raw material, through chemical reactions, is converted into liquid hydrocarbon mixture, which, under further processing, becomes desired liquid fuels or chemical feedstock. Therefore, the main purpose of coal liquefaction lies in production of either synthetic oil as a partial
Abstract. The catalysis of coal liquefaction encompasses many reactions, conditions and catalytic and support materials. Catalytic processes for direct liquefaction of coal recently piloted or demonstrated such as H-coal, have used conventional hydrotreating or hydrofining catalysts such as alumina supported Co-mo1ybdate.
The conversion of coal to “clean” fuels imposes severe demands on materials of construc-tion. The operational environments experienced by these materials may be high tempera-tures and high pressures and contain substantial quantities of H 2 S, H 2, organic acids, chlorides and particulate matter.Experiences to date indicate that corrosion and erosion problems will tax materials
1982-1-1 Direct Liquefaction. Solid coal can be converted directly to a liquid by thermo-chemical treatment, at high temperature and high pressure. This route is called direct liquefaction in contrast to indirect liquefaction involving coal gasification to synthesis gas and subsequent synthesis to liquids. 3.1.1.
The subchronic toxicity of two materials produced by the EDS direct coal liquefaction process was investigated using adult New Zealand white rabbits as the test species. Recycle solvent (RS: 204–427°C) and fuel oil (FO: 204–538°C) were applied to the intact dorsal surface of rabbits, 5 days per week for 4 weeks.
