Hydrogen generation from hydrolysis of sodium borohydride using sulfonated porous carbon as reagent/catalyst
The hydrolysis of sodium borohydride as a source of hydrogen gas is studied at different mole ratios of H+ to NaBH4. The sulfonated porous carbon (SPC) is used as a source of hydrogen ion and catalyst. It is found that the sulfonated porous carbon exhibits high activity for the hydrolysis of NaBH4 to generate hydrogen gas at room temperature in comparison to Amberlyst-15 and Nafion-NR50. The ki...

متن کاملBursting Dynamics in Molecular Hydrogen Generation via Sodium Borohydride Hydrolysis
The hydrolysis of borohydride salts is a promising process for the generation in situ of pure molecular hydrogen that can be used as an alternative fuel. One of the obstacles toward its concrete application in the realm of green energy resides in nonlinear behaviors of H2 delivery during the reaction development. In particular, we have recently shown that this system behaves like a chemical osc...
متن کاملDynamic Modeling of Hydrogen Generation via Hydrolysis of Sodium Borohydride
This paper deals with the dynamic modeling of a hydrogen production system using gPROMS. The model includes mass balances, liquid-gas equilibrium relations, mass transfer laws and kinetic reaction equations. The initial reaction mixture is a sodium borohydride solution that reacts via a self-hydrolysis mechanism in the presence of water. The behavior of this system was measured in terms of prod...
