Cotton-gin trash (CGT) was pyrolyzed at different temperatures (500, 600, 700, and 800°C) using an externally-heated batch reactor that was purged with nitrogen gas at 1000 cm³ min^-1. The average yields of output products (solid/char, liquid/bio-oil, and gaseous) were determined. The heating value (HV) of CGT was measured to be around 15-16 MJ kg^{­ 1} (6500-7000 Btu lb^-1). Gas yield increased as temperature was increased while the effect was opposite on char yield. The maximum char yield of 38% by weight (wt.%) was determined at 500°C and 30 min. The char had the largest fraction in the energy output (70-83%) followed by gas (10-20%) and bio-oil (7- 9%). Maximum gas yield of 35 wt.% was determined at 800°C. The average yield of CO, H₂ and total hydrocarbons (THC) generally increased with increased temperature but CO₂ production decreased. Methane, ethane, and propane dominated the THC. The bio-oil yield at 600°C was the highest at about 30 wt.% among the temperature settings. The HV of bio-oil was low (2-5 MJ kg^-1) due to minimal non-hydrocarbon compounds and high moisture content (MC).
