Is it possible for a single parameter to predict biochar properties?
In the recent publication titled “Carbon-relative molar mass for the modelling of the lignocellulosic biomass torrefaction and slow pyrolysis performance and biochar fuel properties” in the journal Fuel, the authors propose an innovative approach to modelling the biochar production process.
The research aimed to simplify the prediction of biochar efficiency and properties by replacing numerous parameters with a single parameter – CRMM (carbon-relative molar mass)- that integrates biomass elemental composition (C, H, N, S, and O) and ash content.
The research was conducted on the pure structural components of lignocellulosic biomass (lignin, cellulose, and hemicellulose), their mixtures, and actual biomass samples (hardwood, deciduous apple tree, softwood, coniferous pine tree, and hemp straw). Torrefaction and slow pyrolysis processes were performed at temperatures ranging from 200 to 600 °C. Biochar efficiency, composition, and properties were analysed.
The application of a well-defined parameter (CRMM) simplifies biomass thermal processing modelling and enables highly accurate predictions.
The publication indicates that this approach could serve as an alternative to complex models based on numerous factors or artificial intelligence techniques. It may also enhance the clarity of results and the potential for practical implementation.
