Hydrogen production from the hydrolysate of corn stalk by photosynthetic bacteria group

Abstract:

Hydrogen production of photosynthetic bacteria group was studied using corn stalk hydrolyzate as hydrogen production substrate. The affects of sulfuric acid concentration, solid-liquid ratio, hydrolysis time and hydrolysis temperature on hydrogen production were investigated. The optimum process conditions were as follows: the sulfuric acid concentration was 1%, the solid-liquid ratio was 1:12, the hydrolysis time was 0.5 h and the hydrolysis temperature was 110 °C, respectively. Three hydrolyzate detoxification methods were compared and the method of calcium hydroxide obtained the optimal detoxification effect. NH4+ played a stimulatory role to the hydrogen production within certain concentration.
