Co-pyrolysis of lemongrass waste and residual cooking oil was examined in a fixed bed reactor. The goal was to study the effect of pyrolysis parameters on bio-oil yield. Bio-oil product characteristics between lemongrass pyrolysis and residual cooking oil co-pyrolysis were analysed. The variable parameters were temperature (350, 400, 450 and 500 ° C), particle size lemongrass (< 150, 150, 212, 300 and 425μm) and holding time (3, 5 and 7 minutes). The mixing ratios of lemongrass waste to waste cooking oil were respectively 100:0, 90:10, 80:20, 60:40 and 50:50. The optimal temperature was 400 °C with the highest yield of 30.5 percent bio-oil at the particle size of 300 μm, holding time of 5 minutes and the mixing ratio of 80:20. The addition of residual cooking oil increased the quality of the bio-oil obtained in term of phenol compounds.
