  • 4A2. Bituminous Coal Liquefaction Technology (NEDOL)

    Figure 1 shows the progress of coal liquefaction technology since before World War II, expressed by the relation between the severity of the liquefaction reaction and the yield of coal-liquefied oil by generation. As seen in Figure 1, the NEDOL Process is competitive with the processes in .

  • Coal Liquefaction | The Canadian Encyclopedia

    Coal liquefaction is a process that converts coal from a solid state into liquid fuels, usually to provide substitutes for petroleum products. Coal liquefaction processes were first developed in the early part of the 20th century but later application was hindered by the relatively low price and wide availability of crude oil and natural gas.

  • 10.5. Indirect Liquefaction Processes | netl.doe.gov

    Direct coal liquefaction requires an external source of hydrogen, which may have to be provided by gasifying additional coal feed and/or the heavy residue produced from the DCL reactor. Many argue that indirect liquefaction with the current state-of-the-art technologies is more competitive than direct liquefaction.

  • Coal liquefaction - Wikipedia

    Coal liquefaction originally was developed at the beginning of the 20th century. The best known CTL process is Fischer–Tropsch synthesis (FT), named after the inventors Franz Fischer and Hans Tropsch from the Kaiser Wilhelm Institute in the 1920s. The FT synthesis is the basis for indirect coal liquefaction (ICL) technology.
