Abstract

By using heteropoly acid as catalyst and charge carrier

the new high-efficiency biomass electrolysis technology for hydrogen production can electrolyze almost all biomass raw materials to obtain hydrogen

which has the advantages of high efficiency and low energy consumption. Therefore

it has great application value. The experimental system of hydrogen production by electrolysis of biomass using glucose as raw material was established

and a physical model for energy consumption of hydrogen production by electrolysis was established. The hydrogen production performance by electrolysis of glucose was studied from two aspects of hydrogen production rate and energy conversion rate. The results show that

the hydrogen production rate of this technology can reach 58.88 m L/min and the electricity consumption of hydrogen production is calculated to be 2.132(k W·h)/m~3. The energy conversion efficiency can reach 10.465%. In the process of pretreatment

the energy consumption is about 73.187% of the total energy consumption. By analyzing the characteristics of energy consumption of each part

it is proposed to change the pump operation strategy and use solar energy and other renewable energy for pretreatment

which can improve the energy conversion efficiency greatly.
