Abstract
The current study explores co-pyrolysis of sugarcane bagasse, and thermocol waste in a semi-batch reactor to evaluate the influence of temperature, and blending ratio on yield of products, and reaction time, and thereby characterize the maximum liquid product. The properties of liquid product (bio-oil), and the solid product (bio-char) obtained from thermal sugarcane bagasse, and co-pyrolysis sugarcane bagasse: thermocol waste bio-oil were investigated for physicochemical characterizations. The compositional analysis result of the co-pyrolysis liquid product established the presence of several aromatic compounds. The co-pyrolysis liquid product manifested a higher calorific value, carbon, and hydrogen content as compared to sugarcane bagasse thermal pyrolysis bio-oil. The co-pyrolysis liquid product can be used as a liquid fuel in internal combustion engines, as well as a precursor for value-added chemicals. The properties of bio-char suggested it can be used as a solid fuel, as well as an adsorbent.
Highlights
With excel in the world's population, the energy plea is increasing rapidly and it is mainly satiated by fossil fuel sources
The low HHV of Sugarcane bagasse (SB) is owing to high O content, the high HHV in the case of Thermocol waste (TW) is mostly attributed to less oxygen content in the TW sample
The results revealed that, as TW in the blend increased, the bio-oil yield increased, the reason could be due to the synergistic effect coming into play owing to high aromatic content in polystyrene. (Abnisa et al 2013b) investigated the co-pyrolysis of palm shell and polystyrene, wherein they established a synergistic effect between the precursors to be the sole reason for excel in yield of biooil
Summary
With excel in the world's population, the energy plea is increasing rapidly and it is mainly satiated by fossil fuel sources. The use of carbon-neutral and low emission fuel sources like biomass has gained the attention of several researchers all over the world. The co-pyrolysis of biomass and waste plastic is a viable substitute for the generation of high quality bio-oil, as it is simple in operation and required low operating cost. It helps to reduce the wastes generated in society, which are either dump or incinerated, which leads to land/air pollution Abnisa and Wan Daud (2014). The co-pyrolysis of biomass with waste plastic added the synergistic effect which improves the properties of pyrolysis products
