Abstract

Ugljen je heterogeni materijal sastavljen od organskih i anorganskih sastojaka. Anorganski sastojci u obliku minerala i organski vezanih anorganskih elemenata nalaze se u ugljenu kao elementi različitih masenih udjela i elementi u tragovima. Način pojavljivanja i vrste elementa u ugljenu su važan parametar o kojem ovisi ponašanje elemenata za vrijeme pretvorbe ugljena u druge oblike tvari i energije. Anorganski sastojci u ugljenu utječu na tehnološke parametre, okoliš, zdravlje ljudi i postupke recikliranja.
U ovom radu je dan pregled relevantne literature s općenitim informacijama o ugljenu,
pojavnim oblicima, vrsti i sadržaju anorganskih elemenata u ugljenu, načinima njihovog određivanja i utjecaju na okoliš.

Ugljen, kao važan izvor energije i sirovina za proizvodnju drugih ugljičnih materijala i plinova i dalje će se koristiti zbog relativno velikih rezervi. Međutim, postoji sukob između potreba za povećanjem korištenja ugljena s jedne strane i manjeg onečišćenja s druge strane.

Abstract (english)

Coal is a heterogeneous material composed of organic and inorganic constituents. Inorganic ingredients in the form of minerals and organo-bound inorganic elements are found in coal as elements of different weight ratios and trace elements. The appearance and type of elements are an important parameter that depends on the behavior of elements during the conversion of coal to other forms of matter and energy. Inorganic ingredients influence on the technological parameters, environment, human health and recycling processes.
This paper presents a review of relevant literature with general information on coal,
appearance forms, type and content of inorganic elements, methods of their determination and their impact on the environment.
Coal as an important source of energy and raw materials for the production of other carbon materials and gases will continue to be used because of relatively large reserves. However, there is a conflict between the need to increase coal use on the one hand and lower pollution on the other.
