Research Of Iron Oxide Enhanced Cellulosic Biomass Methanogenic

Anaerobic digestion is one of the agricultural waste utilization effective way. Traceelements that affect the performance of organic waste anaerobic biogas importantecological factors, including iron on the efficiency and stability of organic wasteanaerobic fermentation process is the most significant, but often agricultural wastes(such as corn stalks, etc.) containing iron content is very low. Accordingly, the subjectof which the first corn stalks, for example, an amount of initial FeCl3were0.1%,0.2%,0.5%,1.5%,3%,6%(based on the volatile component straw) straw anaerobicfermentation biogas, methane production and biogas slurry residue characteristics. Theresults showed that the initial amount of3%FeCl3, straw anaerobic methane productionefficiency relative to controls (adding0%) increased by14%. X-ray diffraction analysisshowed the presence of FeCl3, cellulose crystallinity biogas is significantly reduced.Biogas composition analysis results indicate the presence of FeCl3help increase cornstover decomposition efficiency of cellulose and hemicellulose, thus improving theefficiency of straw methanogens. The research can provide reference for the use ofagricultural waste methanation.The topic by adding Fe contents were0,0.5%,1.0%,2%iron compounds (goethite,hematite, magnetite and iron hydroxide)(based crispus volatile components) of studythe impact crispus biogas produced by anaerobic fermentation of methane, anotherdosing Fe content of1.0%FeCl2set to the control group. Experimental determination ofthe cumulative amount of methane produced biogas amount of CO2produced, organiccarbon, organic acids, chemical oxygen demand and cellulose enzyme processparameters. The results show that not only can promote goethite crispus anaerobichydrolysis efficiency, but also improve the cellulase activity, in addition to the amountof CO2reflects goethite has improved microbial growth and activity. In addition tobiogas by XRD and component analysis showed that goethite structure of crispus therewas a clear detrimental effect on the efficiency of cellulose and hemicellulosedegradation has significant role in promoting and ultimately improve the anaerobicbiogas system production of methane.
