Abstract

A study of coal upgrading by way of evaporative method using coal from South
Sumatra is conducted. Preliminary inestigation on Upgrading of Brown Coal
(UBC) process using Central and South Banko coals suggests that the process
can be applied to both coals (called S-BK and C-BK) without any operational
problem. It produces high quality-stable coals in the briquette form with a calorific
value of more than 6,500kcal/kg. Moreover, its spontaneous combustion
characteristic is also suppressed comparing to that conventional drying method.
This is due to the addition of aspal (heavy oil) in the solution of kerosene, where
the aspal then soaked in the micropore of to prevent reabsorption of water when
put in the air.
Kata Kunci: upgrading brown coal, Banko coal, briket batubara, spontaneous
combustion
