Keywords: Kraft lignin, lignocellulosic biomass
This research project discusses the technical and economical feasibility of converting kraft lignin to value-added chemicals. Two pyrolysis techniques were implemented: conventional pyrolysis using classical heating and microwave pyrolysis using electromagnetic irradiation. The product distribution and the composition of the bio-oil from the conventional pyrolysis were compared against those from the microwave pyrolysis. Gas chromatography−mass spectrometry analysis was carried out to identify the organic compounds in the obtained oil. To estimate the minimal selling price of the lignin pyrolysis oil and the expected cumulative cash flow at the end of the life cycle of the plant, a first step economics evaluation was completed using the method “net present worth.” Subsequently, different scenarios for reducing the estimated price, which would help for taking a place among the fossil fuel-based chemicals, were debated.
