Abstract

The Batu Ayau Formation in the Kutai Basin has coking coal deposits that have the potential to be processed into coke. Analysis using organic petrography method is an important parameter to identify the composition of the coke product to determine the coke quality. The purpose of this study was to determine the composition of the coke products made from coking coal of Batu Ayau Formation in Kutai Basin, Central Kalimantan. Petrographic analysis on 12 samples obtained in Kal-Teng seam showed that the percentage of coke products varied. Carbon in the binder phase is 85.60 - 92 vol., then the form of carbon in the filler phase is 7.45- 13.64 vol. and a small part of other than carbon material (miscellaneous categories) of 0-0.73 vol. The dominance of inert organic as a filler of the coke wall was identified. The studied coke which is originally made from coking coal with moderate volatile values shows that the coke is ideal in term of its petrographic composition. © Published under licence by IOP Publishing Ltd.
