Abstract EN
Organosolv pretreatment was used to improve solid-state anaerobic digestion (SSAD) for methane production from three different lignocellulosic substrates (hardwood elm, softwood pine, and agricultural waste rice straw).
Pretreatments were conducted at 150 and 180°C for 30 and 60 min using 75% ethanol solution as an organic solvent with addition of sulfuric acid as a catalyst.
The statistical analyses showed that pretreatment temperature was the significant factor affecting methane production.
Optimum temperature was 180°C for elmwood while it was 150°C for both pinewood and rice straw.
Maximum methane production was 152.7, 93.7, and 71.4 liter per kg carbohydrates (CH), which showed up to 32, 73, and 84% enhancement for rice straw, elmwood, and pinewood, respectively, compared to those from the untreated substrates.
An inverse relationship between the total methane yield and the lignin content of the substrates was observed.
Kinetic analysis of the methane production showed that the process followed a first-order model for all untreated and pretreated lignocelluloses.
