摘要:The present invention relates to a method for the synthesis of light aldehyde by the gaseous-phase oxy-dehydrogenation of the corresponding alcohol at a temperature of between 500 and 700°C in adiabatic conditions and in the presence of a metal silver catalyst, characterised in that the oxy-dehydrogenation reaction is carried out in a reactor made of a metal or metal alloy capable of forming a surface layer of chemically inert oxides in nominal operating conditions. More particularly, the metal is selected from titanium, zirconium and tantalum. The metallic alloys include at least 19 wt % or chromium and at least one alloy element selected from aluminium, silicon, manganese, magnesium, wherein the total concentration of said metals is higher than 2 wt %, or selected from the rare earths comprising lanthanum, yttrium, or cerium with a concentration of between 0.1 and 0.5 %

标题:Electrochemical synthesis of ammonia
发明人：DENVIR ADRIAN; MURPHY OLIVER J; CISAR ALAN; ROBERTSON PRISCILLA; USELTON KYLE
摘要:A method for electrochemical synthesis of ammonia gas comprising providing an electrolyte between an anode and a cathode, providing hydrogen gas to the anode, oxidizing negatively charged nitrogen-containing species present in the electrolyte at the anode to form an adsorbed nitrogen species, and reacting the hydrogen with the adsorbed nitrogen species to form ammonia. Preferably, the hydrogen gas is provided to the anode by passing the hydrogen gas through a porous anode substrate. It is also preferred to produce the negatively charged nitrogen-containing species in the electrolyte by reducing nitrogen gas at the cathode. However, the negatively charged nitrogen-containing species may also be provided by supplying a nitrogen-containing salt, such as lithium nitride, into the molten salt electrolyte mixture in a sufficient amount to provide some or all of the nitrogen consumed in the production of ammonia.

发明人：DUBOIS JEAN-LUC
权利人:DUBOIS JEAN-LUC; ARKEMA FRANCE
摘要:The invention relates to a method for the synthesis of dialkoxyalkanes by means of the partial selective oxidation of a light alcohol. According to said method, the light alcohol is oxidized in the presence of molecular oxygen or a gas containing molecular oxygen, and a solid oxidation catalyst based on at least one metal in a reactive medium comprising a gaseous phase containing an acid compound according to the Pearson classification, having a pKa of less than 6.3 in solution in water. The reaction is carried out in a vapor or in a liquid phase.
