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 CrO. 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&#x2014;Co, Cu&#x2014;Ni) and metal oxide, here CrO. 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, CrO.

An electrochemical process for the oxidation of an alkane to at least one corresponding alkene uses an electrochemical cell having an anode chamber on one side of a proton conducting medium, and a cathode chamber on the other side of the said medium. The alkane is oxidized in the anode chamber to produce at least one corresponding alkene and protons are transferred through a proton conducting membrane to the cathode chamber where protons combine with a proton acceptor, while generating electricity and water. An apparatus for use in the process is also provided.

A process and apparatus are described for producing higher hydrocarbons from lower hydrocarbons, e.g. by gas phase electrocatalytic polymerization of methane. This is done using an electrolysis cell having an anode chamber on one side of a solid electrolyte and a cathode chamber on the other side of the solid electrolyte. According to this process, methane-containing gas is passed through the anode chamber to contact a catalytic anode which is connected to one side of the solid electrolyte, this solid electrolyte comprising a solid proton conducting membrane. An inert gas or oxygen is passed through the cathode chamber to contact a catalytic cathode which is connected to the other side of the proton conducting membrane. The membrane is designed so that H,is capable of passing through the membrane from the anode chamber to the cathode chamber.

Electrochemical conversion of hydrocarbons

The invention relates to a process for gas phase electrochemical oxidation of H,S 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 H,S-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&deg; 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.

Electrochemical oxidation of hydrogen sulfide

The present invention relates to the polymerization of one or more alpha olefins in the presence of a transition metal catalyst having either a heterobifunctional ligand, having a phosphorus and a nitrogen atom, or a bis-phosphinimine ligand having two nitrogen atoms, in the presence of an activator.

Phosphorus based catalysts for the polymerization of olefins

The present invention relates to the oligomerization of lower alpha olefins, and particularly ethylene, to higher olefins in the presence of a catalyst precursor having either or both of a dithiophosphinate complex and a heterobifunctional ligand having a phosphine center and an imine or similar center, in the presence of an activator. The catalysts have a high reactivity and a good selectivity.
