We have studied thermal pyrolysis of cogongrass (Imperata cylindrica) at 400°C, 450°C, and 500°C. We have studied the effect of temperature on the yield of solid, liquid, and gaseous pyrolysis products. The maximum yield (33.67%) of liquid product (bio-oil) is obtained at 500°C. The bio-oil contains oxygen-containing compounds with hydroxyl and carboxyl groups: phenol, 2,6-dimethoxyphenol, 2-methoxyphenol, 2-methylphenol, 4-ethyl-2-methoxyphenol, etc.
