Abstract:
1. A method for controlling the dissociation of a flow stream of water into hydrogen and oxygen, comprising: intermittently introducing a flow stream of an aqueous liquid comprising an aqueous solution of alkali metal hydroxide into a reaction vessel and contacting it therein with a quantity of dissociation initiating material; monitoring the temperature, or pressure, or both, in the reaction vessel; monitoring the surfaces area of dissociation initiating material in contact with the aqueous liquid; and controlling the surface area of dissociation initiating material in contact with the aqueous liquid in response to the temperature, or pressure, or both, or in response to changes in temperature or pressure or both, in the reaction vessel by either; (a) adjusting the level of aqueous liquid in the reaction vessel, (b) varying the rate of introduction of aqueous liquid into the reaction vessel, or (c) forcing aqueous liquid out of the reaction vessel in response to an increase in the pressure in the reactor or a combination of these.
