Biochar (BC) recently gained attention as an additive for anaerobic digestion (AD). This work aims at a critical analysis of the effect six BCs, with different physical and chemical properties, on AD mixed wastewater sludge 37 °C, comparing their influence methane production kinetics. batch tests were performed laboratory scale operating 48 reactors (0.25 L working volume) 28 days addition 10 g...

The aim of this study was to determine and compare the digestion kinetics of two fibre sources (lucerne, maize stalk) in different segments of the digestive tract of geese. Sixty Jilin nongan white geese were divided into two groups and fed with a lucerne or maize stalk diet. After 30 days of feeding, all of the geese were fed with Co-EDTA as the marker of liquid digesta, and n-alkane was used ...

Abstract The use of cheap product gas from biomass air gasification to produce methane via anaerobic digestion is a novel and potential pathway for the large-scale production biomass-based substitute natural (BioSNG). In this experimental work, biomethanation (PGB) was studied with respect biosludge enrichment inoculum partial grinding as well mesophilic thermophilic conditions. results show th...
