摘要:A process is described for synthesizing a mixed peroxide or hydroxo-peroxide of an actinyl and at least one cation X1, wherein the actinyl is a uranyl or neptunyl and the at least one cation X1 is a di-, tri- or tetra-charged metal cation. This process includes the reaction in a solvent of a salt of the at least one cation X1 with a compound C2 selected from mixed peroxides and hydroxo-peroxides of the actinyl and of at least one singly charged cation X2, whereby compound C2 is converted to the peroxide or hydroxo-peroxide by replacement of the at least one cation X2 by said at least one cation X1. Also disclosed is a process for synthesizing a mixed oxide of an actinide selected from uranium and neptunium, and of at least one metal able to form a di-, tri- or tetra-charged cation, which implements the preceding synthesis process. The disclosure further relates to a mixed peroxide or hydroxo-peroxide of an actinyl and of at least one di-, tri- or tetra-charged metal cation, and the use thereof for the preparation of a mixed oxide of an actinide and of at least this metal.

摘要:A method of: introducing hydrogen and a feed gas containing at least 50 vol % carbon dioxide into a reactor containing a Fischer-Tropsch catalyst; and heating the hydrogen and carbon dioxide to a temperature of at least about 190° C. to produce hydrocarbons in the reactor. An apparatus having: a reaction vessel for containing a Fischer-Tropsch catalyst, capable of heating gases to at least about 190° C.; a hydrogen delivery system feeding into the reaction vessel; a carbon dioxide delivery system for delivering a feed gas containing at least 50 vol % carbon dioxide feeding into the reaction vessel; and a trap for collecting hydrocarbons generated in the reaction vessel.

摘要:A catalyst system for the conversion of synthesis gas in a single stage to liquid hydrocarbons comprises (a) a copper-containing alcohol synthesis catalyst, (b) an iron-containing modifier for the alcohol synthesis catalyst to promote the formation of hydrocarbons, and (c) a metallosilicate wax cracking catalyst. The alcohol synthesis catalyst (a) can contain thorium, zinc, uranium or zirconium in addition to the copper. The iron-containing modifier (b) can contain an iron-containing zeolite such as ferrierite or an inorganic support containing ferrous or ferric ions. The metallosilicate can be a zeolite or gallosilicate. The zeolite can have a pore diameter of at least 5 Angstroms and can have the faujasite structure. A Group VIIIA metal e.g., Pd may be incorporated on the zeolite to suppress coke formation. A hydrocarbon product from the conversion can be obtained containing at least 70 percent by weight of hydrocarbons in the range C3 to a boiling point of 340 DEG C., and less than 10 percent by weight of methane.
