To evaluate the contribution of GAC to the rapeseed oil degradation, 0.2 g of GAC were added into serum bottles as the experimental group. Fig. 1(a) shown the methane yield for the rapeseed oil anaerobic digestion with or without GAC. Before being transferred, methane yield of GAC-amended group and control group was almost same, but methane yield of GAC-amended group was higher than that of control groups after being transferred. At the beginning, the microorganisms were no differences, so, no

Due to long-chain fatty acids (LCFAs) and acidification, rapeseed oil as a typical lipid in kitchen waste is difficult to be biodegraded by anaerobic digestion. It has been reported that incorporation of some conductive materials into reactors treating complex organic matter could enhance reactor performance. In this study, the aim was to study this possibility of application of granular activated carbon (GAC) in anaerobic digestion of rapeseed oil. As expected, the GAC-amended reactor could significantly improve methane yield and reduce acidification. Besides, the GAC-amended broth could effi...
