Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for pyrolyzing water. 2. Description of the Related Art It is known that water is thermally decomposed into a mixed gas having a volume ratio of oxygen to hydrogen of 1: 2 when its temperature is raised to 2500 ° C. or more. Although it is theoretically known that thermal decomposition occurs when water is placed in the above-mentioned high-temperature environment, there has been no example in which this was specifically realized and utilized. The present invention has been made to propose such a specific example. [0004] A combustion flame of brown gas is brought into contact with a piece of tungsten in water, and the water may be rainwater, tap water, river water, or the like, so-called H _2.
It does not have to be pure and displayed as O. The tungsten piece may be made of tungsten steel, and its form is not limited. However, the larger the contact area of the brown gas with the combustion flame, the larger the amount of thermal decomposition becomes, so the tungsten piece has a corresponding contact area. Should be. [0006] Brown Gas is disclosed in US Pat.
OXY / HYDROG represented by the specification of US Pat.
EN means that the combustion flame of the gas is 260
It is known that it reaches a high temperature of 280 ° C. and continues burning in water. BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a schematic explanatory view to which the present invention is applied. One liter of water is accommodated in a glass container 1 and a pencil-sized tungsten piece 2 is placed in the water to obtain brown gas. When a brown gas flame ignited by ejecting brown gas from the nozzle body 3 was irradiated and brought into contact with the tungsten piece 2, the portion of the tungsten piece 2 contacted by the brown gas flame turned red without melting, and The gas ascended from the part as bubbles in the water. When the bubbles were collected and ignited, it was found that they ignited and burned, and as a result, water was thermally decomposed into a mixed gas of hydrogen and oxygen. In view of the above, if the entire piece of tungsten is heated to a temperature of 3410 ° C. or less, which is the melting point of tungsten, and 2500 ° C. or more, which is the thermal decomposition temperature of water, the heat of the water is reduced. It has been found that a large amount of brown gas is obtained, as compared with a small amount of brown gas consumed, due to the large amount of decomposition. The reason why tungsten rises to a temperature higher than the thermal decomposition temperature of water due to contact with a brown gas flame is unknown, but at least, if water is disposed around tungsten as in the above embodiment, the melting point of tungsten will be lower. It does not reach high temperatures and the water is thermally decomposed. From this, even if the tungsten piece raised to the thermal decomposition temperature is placed in, for example, spray water, it is considered that the thermal decomposition reaction of the spray water is performed regardless of the purpose of use. . Since the present invention has the above-described configuration,
It is possible to provide a water pyrolysis method applicable to various technical fields.
