Abstract:

In recent years, with the continuous growth of coal-fired power generation in China, as the most important solid waste of coal-fired power plants, the emission of fly ash has also increased sharply with the growth of coal consumption. Fly ash is a by-product of burning coal in coal-fired power stations. Large amounts have been discharged from power plants and dumped on reclaimed land or into the sea, posing potential risks to the environment around these areas and causing serious social and environmental problems. On the other hand, the content of aluminum and silicon elements in fly ash is very high, which has a very high extraction value. Due to the special physical and chemical properties of hydrogen, physical adsorption storage of hydrogen energy has the advantages of safety and reliability, rapid adsorption and desorption of hydrogen under mild conditions. In this paper, ZSM-5 zeolite with high crystallinity is directly synthesized by hydrothermal synthesis using fly ash pretreatment and its hydrogen storage performance is studied.

Key words: ZSM-5, Solid waste utilization, Fly ash, Acid treatment, Crystallization time, Hydrogen storage performance
