<![CDATA[Pyrolysis of bamboo (Gigantochloa apus) offers a route for converting lignocellulosic biomass into bio-oil and biochar. This study evaluated the effect of pyrolysis temperature on product yields and selected properties of bamboo-derived products. Dried bamboo powder (250 g) was pyrolyzed in a laboratory-scale fixed-bed reactor without inert-gas flow at 300, 400, 500, and 600 °C for 60 min. Bio-oil was evaluated by yield, pH, density, and viscosity, whereas biochar was analyzed by yield and Fourier transform infrared spectroscopy. The highest bio-oil yield was 18.80% at 400 °C, while biochar yield declined from 25.20% at 300 °C to 9.00% at 600 °C. Bio-oil exhibited weakly acidic pH (5–6), density of 0.8917–0.9168 g cm⁻³, and viscosity of 0.9322–1.2711 cP. FTIR indicated progressive carbonization with increasing pyrolysis temperature. SEM analysis showed that increasing pyrolysis temperature promoted micropore development, as evidenced by wider cavities and thinner cell walls in biochar at 600 °C compared to 300 °C. These results confirm that pyrolysis temperature strongly governs bamboo product distribution and biochar chemical structure.]]>
