Abstract

In this study, we examined the factors influencing hydrogen gas generation from municipal solid waste incineration bottom ash and methods to improve this process. A series of mixing and stirring experiments using bottom ash and water were conducted. The reaction temperature, liquid-solid ratio, stirring rate, and presence or absence of a grinding treatment were set as the experimental parameters. According to the results obtained in the present study, the optimum temperature for efficient recovery of hydrogen gas was 50°C. When the liquid-solid ratio was 5, or exceeded 3, more hydrogen gas was generated. When the stirring rate was 600 rpm, or exceeded 400 rpm, more hydrogen gas was produced. When bottom ash was crushed, the initial gradient of hydrogen gas generation dramatically increased.
