Research Progresses on Hydrogen Production by Anaerobic Fermentation of Algae
Based on the current situation of the increasing number of algae and non-renewable energy shortage,the resource utilization of algae and biological hydrogen production technology were reviewed,including pretreatment methods,influencing factors of fermentation hydrogen production,etc.The existing research results show that the hydrogen produc-tion results are different under different pretreatment conditions,and the comprehensive application of multiple pretreat-ment methods improved the hydrolysis efficiency of algae resulted in higher hydrogen production.The optimization of the factors affecting the fermentation process is conducive to further improving the efficiency of hydrogen production by algal anaerobic fermentation.It is pointed out that algae is an important raw materials for anaerobic fermentation,and the future research should be focused on the main problems of algal anaerobic hydrogen production technology and strategies to improve the hydrogen production efficiency.
