    摘要: Apparatus and operating methods are provided for integrated electrochemical hydrogen separation and compression systems. In one possible embodiment, an electrical connection is initiated between an anode and a cathode of an electrochemical cell. Hydrogen is ionized at the anode to flow protons through a proton exchange membrane to the cathode. The protons are reacted with oxygen at the cathode to form water. The electrical connection between the anode and the cathode is removed, and a power supply is connected to the anode and cathode so that the anode has a higher electrical potential with respect to zero than the cathode. Various methods, features and system configurations are discussed.

    摘要: Carbothermally reduce a metal oxide to its corresponding metal nitride or metal carbide powder in a vertical gravity flow reactor by adding precursor pellets containing the metal oxide, a thermally decomposed binder material and carbon or a source of carbon directly to a heated reaction zone within the reactor. The pellets form a pellet bed, the top of which must be maintained within the heated reaction zone. The binder material is a blend of wheat and corn starches, optionally in conjunction with another binder such as melamine. The binder material thermally decomposes to a carbonaceous residue which functions both as an additional source of carbon and as a binder for the precursor pellets. The reactor may be modified by adding an internal vent line to remove volatile materials from the heated reaction zone before they have an opportunity to condense on internal reactor surfaces.
