Recent advances on value-added biocarbon preparation by the pyrolysis of renewable and waste biomass, their structure and properties: a move toward an ecofriendly alternative to carbon black

Abstract

The production of renewable biocarbon from waste biomass through pyrolysis as a sustainable and ecofriendly alternative to carbon black poses major scientific challenges for value-added uses in plastic and composite industries.

Metal-Free Carbon-Based Nanomaterials: Insights from Synthesis to Applications in Sustainable Catalysis

“…The degree of graphitization of these carbon-materials can be enhanced, in general, by this traditional method of thermal annealing at high temperatures (>2000 °C) . Moreover, the Marsh–Griffiths model has provided a detailed description of the potential changes that might take place in carbon structures during the annealing process. Numerous carbon materials, , such as carbon fibers, carbon soot, and carbon nanotubes, have their high temperature annealing processes thoroughly studied.…”

“…The energy-efficient conversion of waste biomass into biocarbon involves stages, such as feedstock collection and pyrolysis or gasification processes, demanding moderate energy inputs. In contrast, carbon black production heavily relies on energy-intensive processes, such as the combustion of petroleum feedstocks, necessitating substantial energy inputs in extraction, refining, and high-temperature soot particle formation. , …”

“…Specifically, in the context of biocarbons, the precursors, which may include biomass or organic waste materials, undergo a series of complex decomposition reactions during pyrolysis which involve dehydration, depolymerization, and the generation of volatile compounds, ultimately resulting in the formation of biocarbons. 4,5 In most of the cases, pyrolysis temperature affects the electrical conductivity of biocarbons as graphitic carbons with highly crystalline structures are formed at higher pyrolysis temperatures. In addition, the electrical conductivity of biocarbons is affected by the hydrogen to carbon and oxygen to carbon ratios.…”
