Catalytic wet air oxidation (CWAO) of lignin and phenolic composition of wastewater is a useful pathway towards the recovery of valuable compounds. In this study, bamboo lignin was catalytically oxidized to aromatic aldehydes and acetoderivatives; similarly acetovanillone and acetosyringone were oxidized to vanillin and syringaldehyde, respectively. A total product yield of 9.5% from bamboo lignin and a vanillin yield of 51% with greater than 90% selectivity from acetovanillone were achieved. The proposed reaction pathways suggest a two-step route towards the formation of value-added aromatic aldehydes from lignin via degradation of acetoderivatives. The kinetics study for the degradation of acetovanillone and formation of vanillin was reported for the first time in the temperature range of 120–150 °C, with activation energies of 85.29 kJ mol−1 and 120.7 kJ mol−1, respectively. To date, CWAO breaks down the lignin polymer and toxic phenolic compounds reasonably and effectively, producing value-added aldehydes, which could become a potential new route for the recovery of value-added products.

ABSTRACT In this study, a real-time thermogravimetric analyzer was developed for providing insight into the reactivity and gasification process of pine sawdust. The mass loss rate of pine sawdust, syngas composition, and tar compounds in the gasification process were analyzed at different gasification conditions. According to the real-time thermogravimetric analysis, 800°C of the gasification temperature, 0.25 of the equivalence ratio, and 600 kg/(m2·h) of the gasification throughput were regarded as an optimum conditions for the gasification of pine sawdust in a fluidized bed gasifier.
