“…Migliaccio et al 12 reported the gasification characteristic of sewage sludge at different values of oxygen/fuel equivalence ratios in a bench-scale fluidized-bed reactor, analyzed the influence of seasonal fluctuations of sludge chemical composition on the gasification products, and considered that a higher oxygen/fuel equivalence ratio can reduce the tar yield, and the surface area of the bottom ash produced by gasification in a more reducing atmosphere is relatively high. Yan et al 16 studied the effects of K 2 CO 3 and biomass ash on sludge gasification and found that after introducing steam into the simulated real flue gas, the low calorific value reached twice that without steam, and K 2 CO 3 was conducive to promoting the formation of CO.…”

A comprehensive study was conducted to assess the co-gasification characteristics of sewage sludge and high-sodium coal. As the gasification temperature increased, the CO2 concentration was decreased, and the concentrations of CO and H2 were increased, while the change of CH4 concentration was not obvious. As the coal blending ratio increased, the H2 and CO concentrations initially increased and then decreased, while the CO2 concentration initially decreased and then increased. The mixture of sewage sludge and high-sodium coal shows the synergistic effect of co-gasification, and the synergistic effect was to promote the gasification reaction positively. The average activation energies of co-gasification reactions were calculated by the OFW method, and the average activation energy initially decreases and then increases as the coal blending ratio increases. Both fluidized-bed gasification and thermogravimetric analyzer gasification show that the optimum coal blending ratio is 0.6. Overall, these results provide a theoretical basis for the industrial application of sewage sludge and high-sodium coal co-gasification.

“…The three technologies have unique features. Incineration can recover energy from combustion in terms of electricity and heat, while gasification and pyrolysis generate energyrich outputs such as tar and syngas that can potentially be refined or used as fuel (Djandja et al, 2020, Haghighat et al, 2020Liu et al, 2020a, Liu et al, 2020bRacek et al, 2020, Yan et al, 2020. Air and gas cleaning systems are large for incineration but smaller for gasification and pyrolysis, due to the much lower volumes being treated (Liang et al, 2021, Ronda et al, 2019, Wang et al, 2022, Watson et al, 2018, Zheng et al, 2020, Ziółkowski et al, 2021.…”
