Abstract:
:The aim of the present study was to enhance the gaseous energy recovery from sugarcane bagasse. The two stage (biohydrogen and biomethanation) batch process was considered under mesophilic condition. Alkali pretreatment (ALP) was used to remove lignin from sugarcane bagasse. This enhanced the enzymatic digestibility of bagasse to a great extent. The maximum lignin removal of 60% w/w was achieved at 0.25 N NaOH concentration (50°C, 30 min). The enzymatic hydrolysis efficiency was increased to about 2.6-folds with alkali pretreated sugarcane bagasse as compared to untreated one. The maximum hydrogen and methane yields from the treated sugarcane bagasse by biohydrogen and biomethanation processes were 93.4 mL/g-VS and 221.8 mL/g-VS respectively. This process resulted in significant increase in energy conversion efficiency (44.8%) as compared to single stage hydrogen production process (5.4%).
