Hydrogen Production from Corncob by Thermoanaerobacterium Thermosaccharolyticum M18

摘要

This work experimentally used the corncob to product hydrogen with Thermoanaerobacterium thermosaccharolyticum M18. The initial pH of culture medium, particle size of the corncob and NaOH pretreatment condition were researched and optimized to get high yield and efficiency of hydrogen production. Moreover, the structure and composition of the corncob before and after the pretreatment were analyzed and compared by SEM and a fiber quality analyzer. The optimal operation conditions for high-efficient hydrogen production were: medium initial pH 7, particle size of the corncob 0.25mm (60 mesh), 2% sodium hydroxide solution hydrolysis at 90°C for 120 minutes.
