Biobased tar pitch produced from biomass pyrolysis oils

[Display omitted] •Distillate residues from biomass pyrolysis oils were synthesized into renewable pitch.•The biopitch properties closely align with those of coal tar pitch.•Diverse biomasses used allow greater flexibility for biorefineries. Petroleum-based carbon solid materials, such as petcoke and coal tar pitch, have decreased in quality and/or availability due to various factors, such as the declining elemental quality of crude oil and the push towards environmental sustainability. Coal tar pitch acts as a binder in smelting anodes for aluminum production, which contributes significantly to the fossil-based CO2 production globally. In an effort to reduce the carbon footprint of these processes, we synthesized a renewable biopitch based on biomass pyrolysis. In comparison to previous studies on biopitch, we utilized pyrolysis bio-oils with reduced oxygen content (
