    Coal liquefaction has historically been used in countries without a secure supply of petroleum, such as Germany (during World War II) and South Africa (since the early 1970s). The technology used in coal liquefaction is quite old, and was first implemented during the nineteenth century to provide gas for indoor lighting (Speight, 2013a).

    In the present paper, some problem areas in the selection of construction materials for advanced coal conversion systems are reviewed. It is seen that neither the 'pure materials' approach, nor the 'pure design' approach alone can provide a satisfactory solution to a given problem. The need for a collaboration between the materials engineer and the design engineer is indicated.

    Gareth D. Mitchell, in Applied Coal Petrology, 2008. 6.2 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 300–500°C and 1.0 MPa to produce distillate products (Bergius, 1914). During the period of 1914–1925, the process was refined and I. G. Farbenindustrie began ...
