  • Coal liquefaction - Wikipedia

    OverviewMethodsHistorical backgroundEnvironmental considerationsResearch and development of coal liquefactionSee alsoExternal links

    Specific liquefaction technologies generally fall into two categories: direct (DCL) and indirect liquefaction (ICL) processes. Direct processes are based on approaches such as carbonization, pyrolysis, and hydrogenation. Indirect liquefaction processes generally involve gasification of coal to a mixture of carbon monoxide and hydrogen, often known as synthesis gas or simply syngas. Using the Fischer–Tropsch processsyngas i

  • Coal Processing - an overview ScienceDirect Topics

    The characteristics of each coal conversion process must be considered in any attempt at hazard evaluation, as so many different processes have been attempted or projected (see reviews by Parker and Dykstra, 1978; Ghassemi, Crawford and Quinlivan, 1978; NIOSH, 1978a). Each needs to be analysed specifically for the types of wastes produced and how these are distributed to water, air and soil ...
