Method for producing hydrogen gas using steam cracked plant fermentation straw

Abstract

The method for preparing hydrogen by steam-exploded plant straw fermentation in the present invention: In a semi-solid fermentation reactor, the raw material of steam-exploded straw, corn flour, beef peptone and water are uniformly mixed in proportion, and then sterilized, bacteria-suspended liquid inoculation and fermentation treatment to produce hydrogen; the method also includes collecting the produced hydrogen by gas-gathering method; because the raw material used in the present invention is steam-exploded plant straw, which has abundant resources and low price, it effectively solves the problem of The limited amount of organic wastewater resources cannot bear the shortage of main raw materials for biological hydrogen production. At the same time, it can also overcome the defects of low gas production rate and secondary pollution to the environment in the organic wastewater biological hydrogen production technology.

Description

field of invention

[0001] The invention belongs to the field of hydrogen energy preparation methods, and in particular relates to a method for preparing hydrogen by fermentation of steam-exploded plant stalks. Background technique

[0002] Energy and the environment are the most important topics in the sustainable development of human society. In modern times, the main energy sources used by humans have experienced the development of wood, coal, oil and natural gas, and nuclear energy. However, fossil fuels, which still account for the largest proportion, produce a large amount of harmful substances and cause serious environmental pollution. At the same time, with the rapid development of the world economy and population expansion, energy consumption increases exponentially, making fossil energy increasingly scarce. As a result, clean new energy sources have emerged, such as solar energy, wind energy, geothermal energy, and hydrogen energy.
