Continuous flow culture method of industrial biological hydrogen preparing spawn and biological hydrogen preparing system reinforcing method

Abstract

The present invention relates to hydrogen preparation. Material is replenished continuously to spawn fermenting tank to ensure the continuous production of hydrogen producing spawn; nutritious liquid is pumped continuously from the material replenishing tank to the fermenting tank to ensure the continuous supply of spawn culture medium in the nutritious liquid replenishing rate of 0.5 / day; and the spawn cultured continuously in the fermenting tank is pumped continuously with a metering pump fermenting biological hydrogen producing reactor in the rate fitting the nutritious liquid replenishing rate of the fermenting tank. The continuous culturing process has raised hydrogen producing capacity and improved fermenting bacteria structure, and is suitable for industrial hydrogen production.

Description

technical field

[0001] The invention relates to a method for preparing hydrogen. Background technique

[0002] The non-renewable fossil energy such as petroleum, coal and natural gas has been exhausted due to the massive exploitation of human beings, and the sustainable development of human beings urgently needs the development of renewable follow-up energy. With the deepening of people's understanding of social sustainable development and environmental protection, the development of clean and renewable energy has become an urgent need for human beings. Hydrogen is favored in the energy industry due to its outstanding advantages such as cleanness, high efficiency, renewable, abundant resources, and easy storage and transportation. It is considered to be an important pillar of the world's energy system after the 21st century. In the future world energy system, hydrogen energy will play a pivotal role. In recent years, the development and utilization of hydrogen have received...
