Pyrolisis of coal is partial combustion to reduce total moisture, volatile matter and sulfur contens and increase the calorific value of coal. The results of pyrolysis of coal is coke. At the laboratory level studies, pyrolisis done in batch using different calorie, namely 5800, 6000, 6300 kcal/kg and a time of 15-60 minutes and the temperature 400-800°C. Maximum results obtained total moisture (0.44%), fixed carbon (89%), volatile matter (2.4%), sulfur content (undetected) and ash (7.2%). Then applied to the scale miniplant with continuous processes using multitube pyrolisator which are designed to operate in the temperature range 400-800°C and a flow rate of 240-730 kg/h, obtained coal cokes that meets industry quality standards, namely TM (0.42%), FC (90.40%), VM (2.16%), S (not detected), Ash (6.8%) incalori 6300 kcal/h, a flow rate of 240 kg / h and temperatures between 600-700°C
Key words: coal / coke / pyrolisis / solvenisasi / total moisture / fixed carbon / volatile matter / sulfur content
