Claims7
A method for generating hydrogen by the reaction of a metal with an aqueous salt solution comprising:
- a. mechanically forming a powder from a pressed blank of the metal out of the presence of the aqueous salt solution;
- b. introducing said powder as it is formed into said aqueous salt solution.
A method for generating hydrogen by the reaction of metals with an aqueous salt solution comprising:
- a. introducing a pressed metal blank over an aqueous salt solution;
- b. mechanically forming a powder from said metal blank;
- c. adding said powder as it is formed to said aqueous salt solution;
- and
- d. controlling at least one of steps (a) and (b) by the hydrogen pressure generated by the reaction.
A method for generating hydrogen by the reaction of a metal with an aqueous salt solution in a reaction vessel comprising:
- a. feeding a pressed metal blank to the reaction vessel over the aqueous salt solution;
- b. mechanically forming metal powder from said blank whereby said metal powder drops into said salt solution as it is formed;
- c. feeding additional aqueous salt solution to the reaction vessel for reaction with said metal powder as it is formed;
- and
- d. controlling the feed of said salt solution to said reaction vessel by the amount of metal powder formed from said blank.
A method for generating hydrogen by the reaction of a metal with an aqueous salt solution in a reaction vessel comprising:
- a. feeding a pressed metal blank to the reaction vessel over the aqueous salt solution;
- b. mechanically forming metal powder from said blank whereby said metal powder drops into said salt solution as it is formed;
- c. feeding additional salt solution to the reaction vessel for reaction with said metal powder as it is formed;
- d. inducing and maintaining continuous closed circulation of said aqueous salt solution into and out of said reaction vessel.
