The study investigates the thermal pyrolysis of coal and co-pyrolysis of the coal-sawdust blend (100% blend) in a fixed-bed reactor. The pyrolysis od coal and sawdust was performed at 773K, 823K, and 873K temperature and 30Kmin-1 heating rate under nitrogen purge gas (300mLmin-1). Co-pyrolysis coal and biomass was performed at 50%, 100%, and 200% blends at 873K temperature. The pyrolysis and co-pyrolysis products such as liquid and gas was analysed and compared. Coal pyrolysis resulted higher coal char generation with negligible yield of liquid and gas compared to sawdust. However, 100% co-pyrolyzed blend resulted in higher oil yield % with the increase in temperature from 773-873K with conversion % at 37.35% at 873K temperature. It was confirmed that the increase in biomass blending percentage with coal, the conversion % increased to 92.8% for the 200% blend. GC/MS characterization of oil from 100% and 200% blended samples revealed that alkane is the main component along with a remarkable Cp value of 1.094kJkg-1 K- 1 and 0.271kJkg-1 K- 1 obtained at 823K and 873K reaction temperatures respectively. The pyrolysis oil obtained at 873K at higher biomass to coal blended condition contained higher aromatic compounds. Certain rare comp compounds such as 1-Methyl cyclopropane methanol, 3, 3’- Thiodipropanol, 3- Trans-(1,1-Dimethylethyl)-4, Cis, Methoxycyclohexane-1-ol, 1, 1 -Dimethyl-1-Sinacyclobutane, Octadecane, 2,2,4,15,17,17-Hexamethyl-7, 12-Bis (3, 5,5-Trimethylhexyl), 1,4:3,6-Dianhydro-Alpha-D-Glucopyranose, Hexacosyl acetate and 1,2-Benzenediol, 4-Methyl- present in the copyrolysis oil was also a significant observation in this study.
