ABSTRACT

Characterization and experimentation had been carried out to Kotabangun coal, Tenggarong, East Kalimantan.

Characterization is performed by some analysis comprising of Proximate analysis (moisture content, volatile matter, ash content, and fixed carbon), Ultimate analysis (the constituent of C, H, O, N. S) and petrographycal analysis (vitrinite, liptinite and inertinite, vitrinite reflectance), while the experimentation is conducted by using carbonization drum with indirect carbonization used carbonization temperature ranging 400-700^oC for approximately 20 hours.

The result of carbonization (semi coke) indicates that the decreasing of weight of 34.43 % for particle size of 1 cm, 39.58 for particle size of 2 cm, and 36.40 for particle size of 3 cm, while moisture content, volatile matter and sulfur content decreasing weight of 19.53 %, 49.20 % and 17,64 % respectively, while ash content, fixed carbon and caloric value increase of 40.04 %, 27.09 and 20.91 % respectively.

Key words : characterization, experimentation, indirect carbonization, semi coke
