dc.description.abstract | Additives such as glycerol, methanol, acetone, and ethanol were used to prevent NaBO2 from precipitation, and their effects on hydrogen generation properties of NaBH4 hydrolysis were investigated. When the concentration of additives was 5 wt%, the additives such as methanol, acetone, and ethanol could not prevent NaBO2 precipitation. Although glycerol prevented NaBO2 precipitation, conversion efficiency decreased to 78.0% due to its viscosity. Based on test results, hydrogen generation tests were also performed at various concentration of glycerol and methanol to investigate the concentration effects on hydrogen generation properties. As the concentration of glycerol increased from 1 wt% to 3 wt%, conversion efficiency increased owing to additive effect. When its concentration increased to 5 wt%, conversion efficiency decreased due to its viscosity. As the concentration of methanol increased from 5 wt% to 10 wt%, conversion efficiency increased owing to additive effect. When its concentration increased to 15 wt%, conversion efficiency decreased due to NaB(OCH3)4 precipitate. Although conversion efficiency decreased about 1% when 3 wt% glycerol was added, NaBO2 precipitation was prevented. Consequently, addition of 3 wt% glycerol to NaBH4 solution improves stability of hydrogen generation system. | - |
