Summary: Biochar produced from cocoa shells in Papua New Guinea, Peru, and Colombia showed good CO2 capture performance but with a slower adsorption rate compared to commercial activated carbon. The differences in adsorption kinetics may be attributed to the particle size, pore structure, and surface area of the activated carbon. Overall, cocoa shell biochar proves to be a promising option for CO2 capture due to its simplicity in production process and efficient adsorption capacity.

Summary: In this study, biochar prepared from crisp persimmon peel (CPP) using flash-vacuum pyrolysis showed high adsorption capacity and selectivity for cationic dyes. The adsorption process followed a linear pseudo-second-order kinetics and was well described by the linear Langmuir isotherm model. The adsorption was spontaneous and endothermic, with electrostatic and hydrogen bonding interactions playing important roles. CPP biochar demonstrated excellent regeneration characteristics, making it a green, sustainable, highly efficient, and recyclable adsorbent for selective removal of cationic organic dyes.

Summary: The influence of iron additives on microwave-assisted pyrolysis and subsequent microwave-induced discharge is investigated. Fe2(SO4)3 and Fe2O3 act as catalysts during the second stage of pyrolysis, reducing activation energies by 35.5% and 77.3%, respectively. The addition of Fe(OH)3, Fe2(SO4)3, and Fe2O3 promotes the generation of bio-char, bio-oil, and synsgas, respectively. The iron additives enhance initial discharge intensity, with Fe2(SO4)3 showing an 87.6% increase. Additionally, Fe2(SO4)3 and Fe(OH)3 prolong the discharge duration, doubling and tripling it compared to no additives. Microwave discharge also raises the temperature of the bio-char bed layer, reaching a maximum of 834.4 degrees C. This study provides new insights into the value-added utilization of biomass.
