  • Moving bed hydride/dehydride systems
    Patent number: 4178987
    Abstract: Moving bed hydride heat pumps and pressure pumps are described in which a hydride-forming material is transported between two or more reactor vessels. Each vessel can be maintained at a predetermined temperature, and thus, the hydride-forming material may be heated or cooled by moving it into an appropriately heated or cooled reactor vessel. In this way thermal cycling of reactor vessels is reduced or eliminated. Both continuously operating and moving batch hydride pumping systems are disclosed.
