Estimating the term…
A reactor comprising a body made of a heat-resistant material and having an inlet and an outlet for water/moisture gas, having a gas-diffusing member provided in an internal space of the body, and having a platinum coating on an internal wall surface of the body. Hydrogen and oxygen fed from the inlet are diffused by the gas-diffusing member and then come into contact with the platinum coating to enhance reactivity, thereby producing water. A temperature of the reactor is held to be below an ignition temperature of hydrogen or a hydrogen-containing gas. The platinum-coated catalyst layer on the internal wall of the reactor body is formed by treating the surface of the internal wall of the body, cleaning the treated surface, forming a barrier coating of a nonmetallic material of an oxide or nitride on the wall surface, and forming the platinum coating on the barrier coating.
A process for generating water from hydrogen and oxygen in which hydrogen and oxygen are supplied into a reactor equipped with a material having catalytic action to activate a reactivity of hydrogen and/or oxygen and the reactor temperature is maintained below an ignition temperature of hydrogen and gas containing hydrogen to allow hydrogen and oxygen to react and generate water while preventing combustion of hydrogen and oxygen.
A water-generating reactor in which cylinders made of a material having catalytic action that can activate a reactivity of hydrogen and/or oxygen or a material whose surface is covered with the material having the said catalytic action are placed in a casing to form passages through which hydrogen and oxygen flows while making contact with inner wall surfaces and/or outer wall surfaces of the cylinders, and a heater is placed outside or inside of the casing.
A water-generating reactor in which columns filled with granules made of a material having catalytic action that can activate reactivity of hydrogen and/or oxygen:
A water-generating reactor comprising a metal reactor body provided with an inlet and a water and moisture gas outlet and a platinum coating film provided on an inner wall surface of the reactor body, wherein hydrogen and oxygen supplied from the inlet are brought in contact with the platinum coated film to activate a reactivity and water is generated from the hydrogen and the oxygen.
A water-generating reactor comprising a reactor body of heat-resistant material and having an inlet and a water and moisture gas outlet, a gas diffusing member in an internal space of the reactor body, and a platinum coating film on an inner wall surface of the reactor body wherein hydrogen and oxygen supplied from the inlet and diffused by the gas diffusing member are brought into contact with the platinum coating film to activate a reactivity, and water is thereby generated from the hydrogen and oxygen.
A process for controlling temperature of a water-generating reactor which has a catalyst in a casing that can activate reactivity of hydrogen or oxygen and in which hydrogen and oxygen are allowed to react with each other to generate water at high temperatures, wherein an upstream-end temperature of hydrogen and oxygen under reaction in the said water-generating reactor is held lower than that of a downstream-end temperature.
A process for controlling temperature of a water-generating reactor which has a catalyst in a casing that can activate a reactivity of hydrogen or oxygen and in which hydrogen and oxygen are allowed to react at high temperatures to generate water, wherein areas of contact between the catalyst in the casing and a mixture gas are smaller on upstream-end reacting gases than on a downstream-end reacting gases to reduce reaction amounts of oxygen and hydrogen so that a temperature rise at the upstream-end reacting gas is prevented. .
A process for controlling temperature of a water-generating reactor which has a catalyst in a casing that can activate reactivity of hydrogen and/or oxygen and in which hydrogen and oxygen are allowed to react at high temperatures to generate water, wherein a catalytic action of the catalyst in the casing is designed to be smaller on upstream-end reacting gases than on a downstream-end reacting gases to reduce reaction amounts of oxygen and hydrogen so that a temperature rise on the upstream-end reaction gases in the casing is prevented.
A process for controlling temperature of a water-generating reactor which has a catalyst in a casing that can activate reactivity of hydrogen and/or oxygen and in which hydrogen and oxygen are allowed to react at high temperatures to generate water, wherein positions for supplying gases to come in contact with the catalyst in the casing are scattered to reduce reaction amounts of oxygen and hydrogen so that temperature rises of upstream end reacting gas in the casing is prevented.
A process for forming a platinum coated catalyst layer in a water-generating reactor in which a platinum coated film formed on an inner wall surface of a metal reactor body having an inlet as well as a water and moisture gas outlet serves as a catalyst for activating a reactivity of hydrogen and oxygen supplied from the inlet, with the oxygen and hydrogen being brought into contact with the platinum coating film to generate water from the hydrogen and oxygen in the reactor, wherein the inner wall surface of the said metal reactor body is surface-treated by cleaning, then a barrier film of nonmetallic material of oxides or nitrides is formed on the inner wall surface of the reactor body, and thereafter the platinum coated film is formed on the barrier film.
