“…Biochar, a carbon rich substance derived from biomass through thermal pyrolysis, has been used as the fuel of DCFCs. Halouani's group applied biochar derived from almond shell as the fuel of a DCFC with molten carbonate electrolyte and obtained a peak power density of 127 mW cm -2 at 750 ºC [23].…”

“…Several authors [253][254][255] have used biochar as a fuel for direct carbon fuel cells, proving the relationship between biochar properties (e.g., carbon percentage, ash content, surface area, and heating value) and its fuel performances. Xu et al [256] definitively established the direct relation between the thermal degradation of biomasses and their performances in carbon fuels cell by comparing thermogravimetric analysis with empirical data.…”

Biochar is the solid residue that is recovered after the thermal cracking of biomasses in an oxygen-free atmosphere. Biochar has been used for many years as a soil amendment and in general soil applications. Nonetheless, biochar is far more than a mere soil amendment. In this review, we report all the non-soil applications of biochar including environmental remediation, energy storage, composites, and catalyst production. We provide a general overview of the recent uses of biochar in material science, thus presenting this cheap and waste-derived material as a high value-added and carbonaceous source.

“…It is important to modify the physiochemical properties of biochar and design corresponding upgrading approaches based on specific application requirements. For example, high carbon-oxygen groups in biochar favors its application as the carbon material in direct carbon fuel cells (DCFCs) (Elleuch et al, 2015), which can be facilitated by biochar oxygenation. Hence, biochar upgrading serves as an integral part of biochar application.…”

Syngas and biochar production are mainly influenced by temperature, feedstock properties, gasifying agent, pressure, and the mass ratio between gasifying agent and feedstock with temperature being the most significant factor. Increasing temperature generally promotes syngas production while suppressing biochar production. The selection of gasifiers (fixed bed, fluidized bed, and entrained flow) is highly dependent on scale requirement (e.g., volume of feedstock and energy demand), feedstock characteristics (e.g., moisture and ash content), and the quality of syngas and biochar. Updraft fixed bed gasifiers are suitable for the feedstocks with a moisture content up to 50 wt.%. High ash feedstocks such as Indian coal, dried sewage sludge, and municipal solid waste that are not suitable for fixed bed gasifiers, have been successfully gasified in bubbling fluidized bed reactors. Woody biomass is not suitable for entrained flow gasifiers unless specialized feeding methods are employed such as wood torrefaction and grinding followed by the existing feeding methods for pulverized coals, biomass-oil biochar slurry preparation followed by pumping, wood or torrefied wood slurry preparation followed by pumping, etc. Syngas and biochar can potentially be contaminated by NH3, H2S, and tar, which can be removed using catalysts (e.g., Ni-based), metal oxides-based sorbents, and thermal and catalytic cracking methods. Existing syngas and biochar upgrading methods suffered from various problems such as economic infeasibility, limited productivity, and fouling, and future syngas and biochar upgrading methods should be aimed to have the features of reliability, security, affordability, and sustainability, towards the practical, largescale production of syngas-and biochar-based products. One potential solution is to develop integrated systems by combining biochar upgrading and application with syngas upgrading, which warrants an integrated perspective based on both life cycle assessment and economic analysis.
