    Abstract: In a process for preparing an alkali metal or alkaline earth metal salt of an α,β-ethylenically unsaturated carboxylic acid, a) a transition metal-alkene complex is reacted with CO2 to give a metallalactone, b) the metallalactone is reacted with a base to give an adduct of the alkali metal or alkaline earth metal salt of the α,β-ethylenically unsaturated carboxylic acid with the transition metal complex, and c) the adduct is reacted with an alkene to release the alkali metal or alkaline earth metal salt of the α,β-ethylenically unsaturated carboxylic acid and regenerate the transition metal-alkene complex. The base is selected from alkali metal or alkaline earth metal hydroxides and alkali metal or alkaline earth metal superbases. The alkene is, for example, ethene. The transition metal complex comprises, for example, nickel and a bidentate P,P, P,N, P,O or P,carbene ligand, such as 1,2-bis(di-tert-butylphosphino)ethane.

    Abstract: The invention relates to a catalytic high-pressure process for the CO2 reforming of hydrocarbons, preferably methane, in the presence of iridium-comprising active compositions and also a preferred active composition in which Ir is present in finely dispersed form on zirconium dioxide-comprising support material. The predominant proportion of the zirconium dioxide preferably has a cubic and/or tetragonal structure and the zirconium dioxide is more preferably stabilized by means of at least one doping element. In the process of the invention, reforming gas is brought into contact at a pressure of greater than 5 bar, preferably greater than 10 bar and more preferably greater than 20 bar, and a temperature which is in the range from 600 to 1200° C., preferably in the range from 850 to 1100° C. and in particular in the range from 850 to 950° C., and converted into synthesis gas. The process of the invention is carried out using a reforming gas which comprises only small amounts of water vapor or is completely free of water vapor. In the process, the formation of carbonaceous material on the catalyst is greatly suppressed while carrying out the process, as a result of which the process can be carried out over a long period of time without significant decreases in activity occurring.

    Abstract: The invention relates to a nickel hexaaluminate-comprising catalyst for reforming hydrocarbons, preferably methane, in the presence of carbon dioxide, which comprises hexaaluminate in a proportion in the range from 65 to 95% by weight, preferably from 70 to 90% by weight, and a crystalline, oxidic secondary phase selected from the group consisting of LaAlO3, SrAl2O4 and BaAl2O4 in the range from 5 to 35% by weight, preferably from 10 to 30% by weight. The BET surface area of the catalyst is ≧5 m2/g, preferably ≧10 m2/g. The molar nickel content of the catalyst is ≦3 mol %, preferably ≦2.5 mol % and more preferably ≦2 mol %. The interlayer cations are preferably Ba and/or Sr. The process for producing the catalyst comprises the steps: (i) production of a mixture of metal salts, preferably nitrate salts of Ni and also Sr and/or La, and a nanoparticulate aluminum source, (ii) molding and (iii) calcination. The catalyst of the invention is brought into contact with hydrocarbons, preferably methane, and CO2 in a reforming process, preferably at a temperature of >800° C. The catalyst is also distinguished by structural and preferred properties of the nickel, namely that the nickel particles mostly have a tetragonal form and the particles have a size of ≦50 nm, preferably ≦40 nm and particularly preferably ≦30 nm, and are present finely dispersed as grown-on hexaaluminate particles. The catalyst has only a very low tendency for carbonaceous deposits to be formed.
