Biobased tar pitch produced from biomass pyrolysis oils

چکیده
• Distillate residues from biomass pyrolysis oils were synthesized into renewable pitch. The biopitch properties closely align with those of coal tar Diverse biomasses used allow greater flexibility for biorefineries. Petroleum-based carbon solid materials, such as petcoke and pitch, have decreased in quality and/or availability due to various factors, the declining elemental crude oil push towards environmental sustainability. Coal pitch acts a binder smelting anodes aluminum production, which contributes significantly fossil-based CO 2 production globally. In an effort reduce footprint these processes, we based on pyrolysis. comparison previous studies biopitch, utilized bio-oils reduced oxygen content (<15%). Guayule switchgrass served choice, their underwent continuous distillation. Solid extraction remove toluene insolubles (TI), remaining fraction heat treatment ∼ 380 °C. While both biopitches contained trace amounts quinoline (QI), TI amounted 32 – 54 wt%. Coking values exceeded 43 wt% pitches, making them feasible anode utilization. use distilled partially deoxygenated enables biorefineries provide marketable coproduct alongside hydrocarbon fuels.

متن کاملCatalytic Pyrolysis of Tar Model Compound with Various Bio-Char Catalysts to Recycle Char from Biomass Pyrolysis
Tar and char can be regarded as unwanted byproducts during the gasification process. In this study, three types of catalyst, i.e., biomass char (bio-char), nickel supported on biomass (Ni+bio-char), and nickel supported on bio-char (bio-char+Ni), were studied to compare the catalytic effects of different preparation methods on tar model compound removal. The structural characteristics of the th...

متن کاملSANS analysis of the microstructural evolution during the aging of pyrolysis oils from biomass.
In this paper, we report for the first time a microstructural characterization of pyrolysis oils obtained from biomass. Bio crude oils (BCOs) are good candidates as substitutes for mineral oils as fuels. By using small-angle neutron scattering (SANS), we show that BCOs are nanostructured fluids constituted by a complex continuous phase and nanoparticles mainly formed by the association of units...
