摘要:
A sunrays focusing apparatus for obtaining highly condensed solar energy. The apparatus includes a first trough-shaped parabolic reflector mounted for rotation about both vertical and horizontal axes.A first elongated refractor is mounted to the first parabolic reflector along or adjacent to the focal axis of the first parabolic reflector.A second trough-shaped parabolic reflector is also mounted to the first parabolic reflector in such a way that focal axes of both first and second parabolic reflectors are disposed at right angles to each other.A second reflector is mounted to the first parabolic reflector along or adjacent to the focal axis of the second parabolic reflector. Mounted on the second parabolic reflector is a sun tracking device responsive to sunrays for directing the first parabolic reflector towards the sun.

An oxidative autothermal reformer including a reforming layer at least partially filled with a reforming catalyst for producing a reformed gas composed mainly of hydrogen through a reforming reaction by contacting a mixture of a hydrocarbon or an aliphatic alcohol and steam with the reforming catalyst; and an oxidative exothermic layer at least partially filled with an oxidation catalyst for generating heat by oxidizing a part of the reformed gas, in which the reforming layer is disposed at an upstream side of the oxidative exothermic layer; the reforming layer and the oxidative exothermic layer are in the form of a cylinder and have a triple circular tube structure formed by disposing an inner reforming layer, an oxidative exothermic layer and an outer reforming layer from the inside in a radial direction in this order; and at least a part of the reforming catalyst filled in the inner reforming layer and the outer reforming layer contains Ru metal.
摘要:
A method of producing hydrogen by reforming a hydrocarbon or an aliphatic alcohol. The method includes preparing a columnar catalytic member having many axial passages and containing a reforming catalyst, a shift catalyst and an oxidation catalyst; preparing a reformable gas containing a hydrocarbon or an aliphatic alcohol and water vapor mixed together; rotating the columnar catalytic member, while passing the gas therethrough transversely with respect to its cross-section such that the gas first flows along a forward path extending in one direction through a first portion of the axial passages and then flows along a backward path extending in the other direction through a second portion of the axial passages, thereby causing the gas to undergo reforming and shift reactions to form hydrogen for recovery, while the gas makes a round trip along the forward and backward paths; and introducing an oxygen containing gas into the forward path and/or the backward path.

摘要:
An auto-oxidation and internal heating type reforming method and apparatus for hydrogen production are disclosed for use in a process in which a gaseous mixture of a hydrocarbon or an aliphatic alcohol with water vapor is fed into contact with a mass of a reforming catalyst to bring about a reforming reaction of the gaseous mixture to produce hydrogen, wherein a small amount of an oxidizing catalyst is admixed with the reforming catalyst in that mass; and a small amount of oxygen is admixed with the gaseous mixture, whereby a portion of the hydrocarbon or aliphatic alcohol is exothermally oxidized to generate a quantity of heat required to reform the gaseous mixture of the hydrocarbon or aliphatic alcohol with water vapor.

A combustion apparatus comprises: a large-diameter sleeve-like element forming an incoming passage through which an air/fuel mixture gas flows in a predetermined direction; at least one small-diameter sleeve-like element disposed in the incoming passage, which small-diameter sleeve-like element forms an outgoing passage through which a combustion gas having been issued from the incoming passage flows in a direction counter to the above predetermined direction; an air/fuel mixing unit for issuing the air/fuel mixture gas under a predetermined pressure to a main incoming port located in an upstream side of the incoming passage; an auxiliary incoming unit for issuing a combustion gas produced by a pilot burner to the upstream side of the incoming passage prior to supplying the air/fuel mixture gas to the incoming passage; and a combustion-gas outlet port for discharging the combustion gas having passed through the outgoing passage, which combustion-gas outlet port communicates with an outlet opening of the outgoing passage.

摘要:
An apparatus for producing fresh water from sea water in which a vertical accumulator utilizes the sensible heat of sea water so as to evaporate said sea water to a temperature above 100.degree. C. under pressure, a heat-exchanger connecting between the upper and lower portions of said accumulator causes a high temperature liquid to effect heat-exchange with sea water to be evaporated, a fresh sea water feed line connected to the lower portion of said accumulator adjusts the pressure within the accumulator and an evaporator receives higher temperature sea water. The accumulator accumulates heat in such a manner that the upper portion of said accumulator holds higher temperature sea water and the lower portion of the accumulator holds lower temperature sea water so that when heat is accumulated, the amount of said higher temperature sea water increases and when heat is radiated, the amount of higher temperature decreases whereby sea water evaporates at all times.
