Abstract A green and economically viable route without any additional activation agents and templates has been developed to synthesize biomass-derived nanoporous carbon for superior electric double-layer capacitors via direct pyrolysis of dried black liquor powders, which is the main waste in pulping and paper-making industry. The resulting carbon materials present hierarchical porosity and moderate specific surface area of 1134  m 2 g − 1 {\text{m}^{2}}\hspace{0.1667em}{\text{g}^{-1}} , as well as multi-heteroatoms co-doping such as N, S, Na and K, which exist originally in black liquor. When evaluated as electrode materials for supercapacitors in 6 M KOH aqueous electrolyte, the-prepared carbon samples deliver a significantly high gravimetric capacitance of 331  F g − 1 \text{F}\hspace{0.1667em}{\text{g}^{-1}} at 0.5  A g − 1 \text{A}\hspace{0.1667em}{\text{g}^{-1}} in a three-electrode system. Moreover, the fabricated symmetric supercapacitor also possesses a gravimetric capacitance of 211  F g − 1 \text{F}\hspace{0.1667em}{\text{g}^{-1}} at 0.5  A g − 1 \text{A}\hspace{0.1667em}{\text{g}^{-1}} , with an impressive long-term cycling stability of 92 % capacitance retention after 3000 cycles. This work explores a suitable and scalable approach for mass production of high-performance electrode materials with industrial wastes on the base of cost-efficiency and environment-friendship.

AbstractIn the present study, the influence of long-term heat treatment of black liquor with focus on a subsequent lignin precipitation process was investigated. The well-known CO2 approach to precipitate a certain amount of lignin from heat-treated black liquor was studied within defined thermal conditions. Several important characteristics of lignin such as molar mass and functional groups were analysed. Viscosity and buffer capacity of black liquor were also studied. Results showed a reduction in lignin yield as a result of a decrease in molar mass and lignin demethylation after the heat treatment. The acid consumption during precipitation was found to be higher after the heat treatment.
