AVALIAÇÃO DA PRODUÇÃO DE HIDROGÊNIO A PARTIR DA CODIGESTÃO ANAERÓBIA DE RESÍDUOS SÓLIDOS ORGÂNICOS E GLICEROL RESIDUAL DA PRODUÇÃO DE BIODIESEL

The anaerobic co-digestion of solid organic waste with residual glycerol from biodiesel production (1% v v-1) for hydrogen production was investigated by means of the Biochemical Hydrogen Potential (BHP). The specific hydrogen production from co-digestion with and without glycerol corresponded to 140 mL H2 g VS-1 and 87,3 mL H2 g VS-1 removed, respectively, while the maximum specific H2 production rate was found to be 14.26 e 8.57 mL H2 g VS h-1, respectively. Co-digestion of solid organic waste with glycerol enhanced hydrogen production and reduced the fermentation lag phase in around 4 hours...
