    摘要: A method of regenerating an absorbent includes preparing a reactor having a gas inlet portion and a discharge portion, filling the reactor with a reforming catalyst and an absorbent for absorbing carbon dioxide, feeding the feedstock gas and the steam via the gas inlet portion to the reactor to allow a steam reforming reaction to take place, allowing the absorbent to absorb carbon dioxide generated with hydrogen at the steam reforming reaction, and releasing the carbon dioxide from the absorbent after the carbon dioxide absorption capacity of the absorbent has been degraded. In this method, the temperature in an inside of the reactor is set to 625° C. or more at the release of the carbon dioxide, and an inert gas is fed via the discharge portion to the reactor.

    摘要: Disclosed is a system for recovering gas produced during electrodialysis of a saline solution, from gas entrained in an electrolyte solution circulating through anode and cathode compartments of an electrodialysis (ED) unit. In one embodiment, the system provides separate catholyte and anolyte towers within a closed, re-circulating loop between the cathode and anode compartments. Each tower comprises an inlet at which the entrained gas separates from the electrolyte solution and flows into the headspace. One can recover residual gases from the electrolyte solution in one more additional apparatus. Preferably, hydrogen gas is separated from the catholyte solution and, more preferably, further purified for use as a fuel source in alternative power generating devices, such as a fuel cell or bio-fuel generator, useful in the unit operations of a water treatment system.

    摘要: An apparatus and method for drying ethanol includes a first reaction chamber for carrying out the removal of water from wet ethanol, a feed inlet for introducing the wet ethanol into the reaction chamber, a product outlet for removing dry ethanol from the reaction chamber, an optional fuel inlet for introducing a fuel into the reaction chamber, and a particulate bed, including sorbent particles, that is disposed within the reaction chamber. In a preferred embodiment, the bed is divided into first and second zones each provided with different size sorbent particles. In another preferred embodiment, the bed contains a mixture of sorbent particles and catalyst particles. The sorbent particles operate to remove water from the wet ethanol and form hydrated-sorbent particles. The catalyst particles operate to promote chemical reaction of the fuel, generating heat that causes removal of water from the hydrated-sorbent particles and regenerating the sorbent particles.
