Fossil carbon and coal in particular is sedimentary rock of vegetal origin. Coal contains 65-67% of carbon, 26% of hydrogen, 1.5-15% of oxygen, some sulfur and nitrogen. Coal is used as fuel after enhancement by coking or gasification. The paper discusses contemporary use of coal as a chemical substance and energy carrier. Keywords: carbon, coke, gas generation, gas generator, hydrogen addition, reactor, pyrolysis. Anglys (iskasamosios anglys), o ypac ju grupe-akmens anglys, yra augalines kilmes nuosedine uoliena. Joje yra 65-97 % anglies, 26 % vandenilio, 1,5-15 % deguonies, taip pat sieros ir azoto. Anglys naudojamos kaip kuras, jos perdirbamos koksuojant bei gazifikuojant. Siame tekste pateikiami siuolaikiniai duomenys apie anglies, kaip chemines zaliavos ir energijos nesiklio, panaudojima ja koksuojant ir dujinant, taip pat apie siu procesu vystymasi ir tobulejima. Reiksminiai zodziai: akmens anglies dujinimas, hidrinimas, koksavimas, pirolize, reaktorius, regeneratorius.
