Abstract
Anaerobic digestion of lignocellulose feedstocks requires a lengthy period, and the process's efficiency is always low without catalysis. Therefore, this study investigated the influence of chemical pretreatment methods on the methane yield of Arachis hypogea shells using H2SO4 and NaOH. The pretreated substrates were digested in a lab-batch digester for 30 days at mesophilic temperature (37 ◦C). The optimum methane yield of 205.22 ml/gVSadded was recorded at 0.5% (v.v-1) H2SO4 for 15 min, while 3% (w/w) NaOH treatment for 15 min released the optimum methane yield of 256.78 ml/gVSadded.
