Abstract

Coal mines in Jambi Province are located in Bungo and Sarolangun regencies. Coal obtained from these two districts has a calorific value of coal ranging from 4,700 – 6,300 cal / g which is included in low-rank coal. To increase the calorific value of low-rank coal, the Upgrading Brown Coal (UBC) method is used. UBC technology is one method of utilizing low-rank coal by reducing water content so that it will directly increase the calorific value of coal. The UBC process uses the hydrothermal-slurry dewatering method using residual oil additives from polypropylene (PP) plastic oil cracking. The coal used as much as 50 g with the addition of additives with variations (10, 15, 20, 25 and 30 mL) is then ovened in the slurry-dewatering process with variations (130, 140, 150, 160 and 1700C). The results showed that the calorific value of coal increased to 7,155 Kcal/Kg at a temperature of 1700C, while for the lowest moisture content at a temperature of 1400C which was 8.73% with a ratio of coal and additives (50 g: 20 mL). This increase in calorific value and decrease in levels shows that additives have succeeded in covering the pores of coal and reducing the water content in coal as evidenced by SEM-EDX and FTIR analysis. The analysis results show that the pores of coal have been filled with additives and the abundance of C-H and C=O groups is reduced. In the Moisture Readsorption Ratio analysis) coal after upgrading with a storage time of 5 days there was an increase in moisture content of 3,83%.
