The Decompositioning of Volatile-Matter of Tanjung Enim Coal by using Thermogravimetry Analyzer (TGA). Coal is a nature material which a kind of energy source. The decompotition of coal could analyze by heat treated using thermogravimetry analyzer. The decomposition of the volatile matter for three kinds of Tanjung Enim coal could be known. The value of activation energy that be found diference, then for Semi Anthracite, Bitumonius and Sub Bituminous Coal, the initial temperatures are 60.8 oC, 70.7 oC, 97.8oC, and the last temperatures are 893.8 oC, 832 oC, 584.6oC.

Bahasa Abstract

Batubara adalah material alam yang merupakan sumber energi. Perilaku perubahan komposisi atau dekomposisi material batubara dapat diamati dengan cara memanaskannya dengan memakai alat thermogravimetry. Tiga jenis batubara Tanjung Enim dapat diketahui dekomposisi volatilnya. Dengan besaran energi aktivasi yang berbeda, maka masing-masing untuk batubara Semi Antrasit, Bitunimus dan Sub Bituminus menunjukkan temperatur awal devolatisasi yaitu 60,8 oC, 70,7 oC, 97,8 oC dan temperatur akhir devolatisasi masing-masing 893,8 oC, 832 oC, 584,6 oC.
