摘要: Anode catalysts for conversion of hydrocarbon feeds in solid oxide fuel cell membrane reactors. An anode catalyst may be a mixture of a metal with a metal oxide, for example a mixture of copper or copper-nickel alloy or copper-cobalt alloy with Cr2O3. Mixed oxides can be prepared by dissolving into water soluble salts of the different metals, chelating the metal ions with a chelating agent, neutralizing the solution, removing water by evaporation to form a gel which then is dried, and finally heating the dried gel to form a mixed oxide of the different metals. The chelating agent can be citrate ions, and ammonia can be added to the solution until the pH of the solution is about 8. The mixed oxide so formed then is reduced, for example by hydrogen, to form a composite comprising the metal (Cu, Cu—Co, Cu—Ni) and metal oxide, here Cr2O3. Typically, the composite oxides so formed comprise approximately spherical nanoparticles, and the reduced composites are nanoparticles comprising very small particles of the metal within a network of the oxide, Cr2O3.

摘要: The invention relates to a process for gas phase electrochemical oxidation of H2S to sulfur and water or steam using an electrolysis cell having an anode chamber on one side of a solid proton conducting membrane and a cathode chamber on the other side of the membrane. The process comprises the steps of passing H2S-containing gas through the anode chamber to contact a catalytic anode, where it reacts to produce elemental sulfur, protons and electrons. The protons pass through the membrane from the anode chamber to the cathode chamber. An oxygen-containing gas is passed through the cathode chamber to contact the catalytic cathode, where it reacts with protons and electrons to produce water or steam. During the process, both the anode chamber and cathode chamber are maintained at a temperature of at least 120° C. and an elevated pressure sufficient to keep the membrane moist. Sulfur is obtained in liquid or vapor form and is removed from the anode chamber while water or steam is removed from the cathode chamber. An electric current can be withdrawn from the anode and cathode. The cell can also be operated in the electrolysis mode to produce sulfur and hydrogen.

摘要: Propylene glycol methyl ether is produced by feeding a solution of a basic catalyst in methanol to a catalytic distillation column containing a heterogeneous basic catalyst defining a heterogeneous reaction zone, and feeding propylene oxide to the column. The methanol reacts with the propylene oxide according to a dual homogeneous catalytic reaction and heterogeneous catalytic reaction to form propylene glycol methyl ether, which is removed from the column as a bottoms product. Alternatively, methanol can be reacted with propylene oxide in a pre-reactor, to form propylene glycol methyl ether, and, when the temperature in the pre-reactor reaches about 100° C., the reaction products are transferred to the catalytic distillation column for further reaction.

摘要: A process and apparatus is provided for reduction of dissolved oxygen content in seawater from about 8 ppm in the feed seawater to about 10 ppb or less. Significant advantages are achieved by: use of a separator in horizontal alignment to provide high gas-liquid contacting area for separation and de-entrainment within the separator, thereby providing higher throughput; and heating seawater to at least 30° C. and up to 60° C., so as to enhance removal of oxygen from seawater; use of once-through fuel gas as stripping gas and its subsequent combustion for heating the seawater provides for high efficiency and reduction of fouling. The combination of these features allows the amount of residual oxygen in deoxygenated seawater to be reduced to below 10 ppb and as low as 2 ppb.
