Abstract
A hydrogen storage composition is provided which defines a physical sol-gel matrix having an average pore size of less than 3.5 angstroms which effectively excludes gaseous metal hydride poisons while permitting hydrogen gas to enter. The composition is useful for separating hydrogen gas from diverse gas streams which may have contaminants that would otherwise render the hydrogen absorbing material inactive.
Claims14
A composition for absorbing hydrogen, said composition made by a process comprising the steps of:
- adding a hydrogen absorber to a sol;
- agitating said sol to disperse said hydrogen absorber throughout said sol;
- gelling said sol to form a gel with said hydrogen absorber dispersed throughout said gel;
- and
- seasoning said gel in a sealed container until a liquid phase has formed;
- and
- heat treating said gel to form a porous glass matrix with said hydrogen absorber dispersed throughout, said matrix defining an average pore size sufficient to admit hydrogen gas while excluding gaseous metal hydride poisons.
4 more elements
A composition for absorbing hydrogen, said composition comprising:
- a porous glass matrix having an average pore size sufficient to admit hydrogen gas while excluding gaseous poisons;
- particles of a hydrogen absorbing material distributed throughout said glass matrix and in communication with said pores.
