摘要: This study compares the effects of pure kraft lignin and lignin/silica system (1:4 by weight). The comparative analysis physicochemical properties both carriers showed that was characterised better properties. experiment conducted in involved continuous anaerobic digestion under mesophilic conditions. Three samples were degraded following order: (i) sewage sludge (SS), (ii) SS with addition lignin, (iii) system. A quantitative digestate carried out means situ fluorescence. It more intense proliferation microorganisms + variant than sample lignin. highest amount biogas obtained (689 m3 Mg−1 VS, including 413 VS methane; VS—volatile solids). There comparable amounts (526 biogas, 51% methane) (586 54% methane). research clearly material a high share silica an effective cell carrier.
