Lurgi–Ruhrgas process - Wikipedia

The Lurgi–Ruhrgas process was originally invented in the 1940s and further developed in the 1950s for a low-temperature liquefaction of lignite (brown coal). The technology is named after its developers Lurgi Gesellschaft für Wärmetechnik G.m.b.H. and Ruhrgas AG.Over a time, the process was used for coal processing in Japan, Germany, the United Kingdom, Argentina, and former Yugoslavia.

Coal - Wikipedia

Coal is a combustible black or brownish-black sedimentary rock usually occurring in rock strata in layers or veins called coal beds or coal seams.The harder forms, such as anthracite coal, can be regarded as metamorphic rock because of later exposure to elevated temperature and pressure.Coal is composed primarily of carbon, along with variable quantities of other elements, chiefly hydrogen ...
