Abstract

The invention provides a method for preparing hydrogen by fermenting biologically pretreated straw, wherein, trichoderma is utilized to carry out biological pretreatment on straw, the biologically pretreated straw is mixed with un-treated straw, and then the hydrogen is prepared by fermenting the mixed straw and hydrogen sludge. As the method utilizes the crop straw as the raw material, the resource of the straw is rich and the price of the straw is low, thereby effectively solving the problem concerning the resource of biological hydrogen preparation; meanwhile, the method also overcomes the defect that when conventional straw fiber material is used in the hydrogen preparation process, the efficiency is low; and the method has the advantages of simplicity, high efficiency, energy conservation, low cost, and the like, and can improve the hydrogen yield rate by 50 percent to 120 percent.

Description

technical field

[0001] The invention relates to a method for preparing hydrogen, in particular to a method for preparing hydrogen by using biological pretreatment straws by fermentation. Background technique

[0002] Hydrogen energy is a completely clean new energy and renewable energy. Hydrogen can be directly used as fuel, or can be directly converted into electrical energy by electrochemical reaction through fuel cells for power generation and transportation, etc. Hydrogen can also be used as an intermediate carrier for various energy sources. When hydrogen is used as a fuel for transportation, heat energy and power production, it has the characteristics of high efficiency and high efficiency, and the reaction products of hydrogen are water and heat, which is a real clean energy and sustainable energy. Sustainable use, environmental protection, reduction of air pollution and mitigation of the greenhouse effect will have a revolutionary impact. Due to the depletion of co...
