چکیده انگلیسی
Alkaline pretreatment with NaOH was used to improve methane yield from Pennisetum Hybrid. The pretreatments were carried out with different NaOH solutions (2-8%â¯w/w) at three temperatures (35, 55 and 121â¯Â°C) for different periods of time (24, 24 and 1â¯h). All treated and untreated Pennisetum Hybrid were digested under mesophilic conditions (37â¯Â°C) to biogas, significant effects of the pretreatments on the yield of methane were observed. Results showed the modified Gompertz equation was reliable (determination coefficients (R2) greater than 0.96) to describe the kinetic behavior of anaerobic digestion of Pennisetum Hybrid. The best result, obtained by the treatment at 35â¯Â°C 2% NaOH for 24â¯h, resulted in the methane yield of 301.7â¯mL/g VS, corresponding to 21.0% improvement in the methane yield. Compositional, SEM, XRD and FTIR analysis confirmed that lignin removal, structural modification and cellulose crystalline variation were responsible for the improvement.
