摘要： A syngas cleanup section includes a water-gas shift reactor, a first operation unit and a second operation unit. The first operation unit includes a high permeance membrane with H2/CO2 selectivity in flow communication with the water-gas shift reactor to provide a H2-rich permeate stream and an H2-poor retentate stream. The second operation unit recovers H2 and CO from the retentate stream to produce a single, CO2-rich product stream, the entire content of which has a minimum pressure of at least about 10.0 bar. In one embodiment, the second operation unit includes a membrane with Knudsen selectivity for permeating H2, CO and CO2. In this embodiment, the permeate streams are combined to produce a H2 and CO-rich fuel stream used by a combined cycle power generation unit to produce electricity, and the retentate stream is sent to a catalytic oxidation unit to produce the CO2-rich product stream. In another embodiment, the second operation unit is the catalytic oxidation unit.

摘要： Methods for treating water to remove radium include contacting the water with a magnetic adsorbent comprising manganese oxide(s), and applying a magnetic field to separate the magnetic adsorbent from the water, whereby radium is removed from the water. The methods may additionally include regenerating the magnetic adsorbent, and contacting the water with regenerated magnetic adsorbent. Alternately, calcium and/or strontium may be precipitated as carbonate salts from lime-treated water containing radium and barium without precipitating a significant fraction of the barium or radium; and removing radium from calcium- and strontium-free water by precipitating the barium and radium as carbonate salts. The barium- and radium carbonate precipitate may be redissolved in hydrochloric acid and disposed of by deep-well injection.

摘要： A solid oxide fuel cell is disclosed. The fuel cell includes a porous anode, formed of finely-dispersed nickel/stabilized-zirconia powder particles. The particles have an average diameter of less than about 300 nanometers. They are also characterized by a tri-phase length of greater than about 50 μm/μm3. A solid oxide fuel cell stack is also described, along with a method of forming an anode for a solid oxide fuel cell. The method includes the step of using a spray-agglomerated, nickel oxide/stabilized-zirconia powder to form the anode.
