Abstract Biochar is the porous, carbonaceous material produced by thermochemical treatment of organic materials in an oxygen‐limited environment. In general, most biochar can be considered resistant to chemical and biological decomposition, therefore suitable for carbon (C) sequestration. However, assess C sequestration potential different types biochar, a reliable determination their stability needed. Several techniques assessing have been proposed, e.g. proximate analysis, oxygen (O):...
Abstract This study aimed to investigate the extent which it is possible marry two seemingly opposing concepts of heat and/or power production from biomass with carbon sequestration in form biochar. To do this, we investigated effects feedstock, highest heating temperature ( HTT ), residence time at and carrier gas flow rate on distribution pyrolysis co‐products their energy content, as well potential Biochar was produced wood pellets WP ) straw SP temperatures (350 650 °C), three times (10,...
Abstract The characterization of biochar has been predominantly focused around determining physicochemical properties including chemical composition, porosity and volatile content. To date, little systematic research done into assessing the that directly relate to its function in soil how production conditions could impact these. aim this study was evaluate pyrolysis can influence biochar's potential for enhancing benefits by addressing key constraints, identify synergies restrictions. do...
This work aimed to investigate the impact of highest treatment temperature (HTT), heating rate, carrier gas flow rate and feedstock on composition energy content pyrolysis assess whether a self-sustained system could be achieved through combustion fraction alone, leaving other co-products available for alternative high-value uses. Calculations based showed that process sustained by contained within gases alone. The lower limit (6% biomass higher value (HHV)) was surpassed at ⩾450 °C while...
Abstract The energy efficiency of torrefaction/pyrolysis biomass to fuel/biochar was studied using conventional (slow) and microwave (low temperature) pyrolysis. Conventional pyrolysis is approximately three times as efficient pyrolysis, in terms the required process a unit feedstock. However, this more than compensated for by higher content condensable gaseous coproducts from these can be utilized generate electricity drive process. It proposed that most method torrefaction/biochar...
