Abstract

Proximate and ultimate analyses showed that Chandgana Tal coal has the following properties; Wa-13.29%, Ad-12.43%, Vdaf-44.98%, Qdaf-5914 kcal/kg, C-67.56%, H-5.79%, S-1.67%, N-1.18% and O-23.8%. Pyrolysis of coal was performed at 200-700оС using small quartz reactor. With increasing temperature of pyrolysis, the yield of hard residue decreased, while the yield of tar and pyrolytic water increased. The yield of coal tar was maximum at 700оС, and reached 4.8%. At this stage, coal was pyrolized in a bigger scale retort of laboratory. The tar was separated from water and analysed by FT-IR and organic composition.
Thermolysis experiments were also performed in order to explore the possibility of obtaining liquid products under mild condition. The results show that 23.5% of liquid product can be obtained at 450оC with coal to tetralin ratio (1:1.8).
