A dark fermentation photosynthesis combined hydrogen production device and hydrogen production method

technical field

The invention relates to the technical field of agricultural engineering energy utilization, in particular to a dark fermentation photosynthesis combined hydrogen production device and a hydrogen production method thereof.

Background technique

Energy shortage and environmental pollution caused by energy production and consumption have become the two most serious problems faced by human beings in the 21st century, and the development of new energy is imminent. Among all alternative energy sources, hydrogen is recognized by the energy industry as the most ideal alternative energy source for fossil fuels due to its clean combustion, high energy density, and renewability. Traditional hydrogen production technologies mainly include hydrogen production by electrolysis of water and hydrogen production by fossil fuels, that is, hydrogen production by chemical method, which needs to consume a large amount of non-renewable resources such as electric energy, oil, natural gas and coal, which is costly and difficult to get rid of the need for fossil energy. dependency. At the same time, the production process will pollute the environment and cannot meet the requirements of sustainable development. The biological hydrogen production technology is considered to be the most advanced technology because of the advantages of using agricultural waste as raw material for hydrogen production, mild reaction conditions, environmental friendliness, and no consumption of mineral resources. New energy technologies with potential and development prospects will be the main form of hydrogen energy production in the future.

According to incomplete statistics, the total amount of straw resources in my country is about 700 million tons per year. It is estimated that the annual output of crop straw in my country will reach 1 billion tons by 2015, but only about 2% of crop straw is used for new energy production, such as straw power generation. , straw biogas fermentation, etc., and most of the rest are discarded or incinerated, which wastes resources and causes environmental pollution. Using straw biomass as raw material for biological hydrogen production has good development potential.

Relevant studies have shown that the final products of dark fermentation bacteria after decomposing glucose are mostly organic acids such as formic acid, acetic acid, butyric acid, and except formic acid can be further decomposed into _H2 and _CO2 , other organic acids cannot continue to decompose, because the reaction Only in the direction of decreasing free energy. This is the root cause of the low hydrogen production efficiency of anaerobic bacteria, which is the main obstacle in the practical application of dark fermentation hydrogen production technology, while photosynthetic bacteria can use solar energy to overcome the further decomposition of organic acids. The positive free energy barrier allows the organic acid to be completely decomposed and release more hydrogen. On the other hand, because photosynthetic bacteria can only use glucose and a small number of small molecule organic acids, they cannot directly use complex organic substances such as starch, cellulose, and hemicellulose; while anaerobic bacteria can decompose almost all organic substances into small molecule organic acids. Therefore, combining anaerobic bacteria and photosynthetic bacteria with certain technical means and methods to jointly produce hydrogen, so as to complement each other's advantages, will be a key research direction for hydrogen production from biomass in the future.

With the rise of dark fermentation and photosynthesis two-step combined biohydrogen production, the reactor for dark fermentation and photosynthesis two-step combined biohydrogen production will also become a research hotspot. At present, there are few domestic researches on the combined dark fermentation and photosynthesis two-step biohydrogen production reactor, and the actual reactor design is often carried out based on experience.
