Abstract
A feasible and economic method of producing hydrogen and oxygen as potential fuels, from water. The process employs as the energy source, sunlight, which is separated into its infrared portion and its ultraviolet light portion. These are concentrated, and in a first stage the infrared is used to heat the water, under pressure to a superheated steam which is contacted with a steam decomposition catalyst in a chamber which is subjected to concentrated ultraviolet light. The result is separation of the water by a combination of thermal energy and photolytic effect into its component elements, hydrogen and oxygen, which can be collected individually and used as fuel sources.
Claims5
A feasible economic method of producing hydrogen and oxygen from water, said method comprising:
- separating sunlight into ultraviolet light and infrared light;
- concentrating said separated infrared light and said separated ultraviolet light;
- placing water in an enclosed reactor vessel;
- using said separated and concentrated infrared light as a heat source to convert water to steam;
- placing said steam in a second reactor vessel which is at least partially transparent to ultraviolet light and continually subjecting said steam to infrared light to superheat said steam to catalytic decomposition temperatures of about 800.degree. C.;
- contacting said superheated steam, with a steam decomposition catalyst comprising a finely divided heavy metal, or a salt or oxide of a heavy metal selected from the group consisting of Group IIIB, Group IVB, Group VB, Group VIB, Group VIIB and Group VIIIB of the Periodic Chart;
- introducing said concentrated ultraviolet light into said second reactor to separate said steam, in the presence of said decomposition catalyst, into its component parts of hydrogen and oxygen;
- and collecting the hydrogen and the oxygen.
