A method and apparatus is disclosed for feeding solid materials against high pressures wherein a compressible solid is continuously conveyed through a screw extruder having a design compression ratio of from about 50 to about 100 percent of the compression ratio of the solid material being conveyed.

Method and apparatus for continuous pumping of compressible solids

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.
