Abstract:
Three synthesized functional materials,such as Fe
2O
3,Silicalite-1 and Fe
2O
3@Silicalite-1 are investigated for subsequent promotional effects upon gas generation by utilizing organic waste(chicken manure)in anaerobic fermentation for the first time.The results exhibited that the daily biogas yield and methane contents are effectively improved by using functional materials compared with the blank groups.Among them,the Fe
2O
3@Silicalite-1 demonstrated the best performance in terms of the maximum cumulative gas yield and methane contents are increased by 41.39%and 17.24%compared to date of blank group,respectively.Fe
2O
3group increases by31.07%and 10.34%,and Silicalite-1 increases by 23.98%and 12.07%when compared with the date of blank group,respectively.As opposed to agglomeration of nanoparticles in traditional methods,nanostructured Fe
2O
3dispersed on the surface of porous material Silicate-1 could be employed as an effective anaerobic fermentation catalyst against deactivation caused by agglomeration and hence maintains superior performance.Therefore,the energy and environmental benefits of organic waste treatment process could be accomplished by smart tailoring of composite materials with anaerobic fermentation technology.
