Impact of Biochar Type, Biochar-Kraft Lignin Ratio and Reactor Temperature on Microwave Pyrolysis of Kraft Lignin

Short Introductive summary

The current petrochemical consumption is damaging the ecosystem. Bio-oil represents an alternate source of key chemical compounds applied in several industries. In this project, the first phase i.e., microwave pyrolysis of Kraft lignin (KL) in presence of wood biochar is being carried out to obtain bio-oil with lower moisture and higher aromatic organic content. The innovation of this study is investigating the impact of using spruce and hemp biochar, at varied ratios and operating temperatures, on the yield and composition of the bio-oil. The final goal of this project is to synthesize a bio-oil that can be taken as a precursor material for conversion into a novel bio-based thermoplastic polymer. At this stage, the observation and primary quantitative results are available to be discussed. Spruce biochar demonstrated a higher average KL bio-oil yield at all power levels compared to hemp biochar. With increasing power level from 300 W to 600 W, the bio-oil yield increased while the biochar yield reduced. 50:50 ratio of KL and wood biochar feedstock exhibited the highest bio-oil yield. Further testing is being conducted to analyze the biochar and bio-oil composition.
