The exploration of new renewable energy resources has been increasingly performed due to the depletion of the fossil fuels. Biomass as a carbon neutral, environmentally friendly and widely available feedstock has been considered as a promising energy resource that could be converted to liquid fuels, e.g., bio-oil through a pyrolysis technique. The importance of the mass and heat transfer during the pyrolysis was investigated in the production of the bio-oil from water hyacinth with different particle sizes (in the ranges of 1000-10,000 μm and 350-850 μm) at various temperatures (400-650 oC). This study showed that the smaller particle size of water hyacinth-based biomass could result in a higher yield of the bio-oil by 26.46%. Moreover, the yield of bio-oil increased by increasing pyrolysis temperatures from 28.2 wt% at 400 oC to 35.8 wt% at 650 oC. Despite of the increase of the bio-oil yield, the density of the bio-oil produced from the pyrolysis of water hyacinth at 400-650 oC was not significantly different (by ∼8%). The similar trend was applied for the viscosity of the bio-oil; no significant difference of the viscosity of the bio-oil (by ∼15%) was observed. It was probably due to predominant light components in the bio-oil. © 2023 Author(s).
