  • Patent number: 11511266
    Abstract: [Mn3SrO4] cluster compounds are synthesized in a single step from raw materials consisting of simple and inexpensive Mn2+, Sr2+ inorganic compounds and carboxylic acids by using permanganate anion as oxidant. This step can be followed by the synthesis of asymmetric biomimetic water splitting catalyst [Mn4SrO4] cluster compounds in the presence of water. The [Mn4SrO4] cluster compound can catalyze the splitting of water in the presence of an oxidant to release oxygen gas. The neutral [Mn3SrO4](R1CO2)6(R1CO2H)3 cluster compound can serve as precursors for the synthesis of biomimetic water splitting catalysts, and can be utilized in the synthesis of different types of biomimetic water splitting catalysts. [Mn4SrO4](R1CO2)8(L1)(L2)(L3)(L4) cluster compounds can serve as artificial water splitting catalysts, can be utilized on the surface of an electrode or in the catalyzed splitting of water driven by an anoxidant.

  • Patent number: 11434141
    Abstract: The invention relates to a method for the synthesis of ammonia, in which a fresh gas consisting largely of hydrogen and nitrogen is compressed via a compressor and subsequently fed to an ammonia converter for conversion into a converter product containing ammonia and comprising hydrogen and nitrogen. Upstream of the compressor, ammonia is evaporated into the fresh gas in order to cool the fresh gas and to produce a cold substance mixture comprising ammonia and the fresh gas. The substance mixture is heated in a heat exchanger against at least one process stream to be cooled, and subsequently compressed via the compressor, to obtain a compressed substance mixture comprising ammonia and the fresh gas. Upstream of the circuit cooler, a gas mixture consisting largely of hydrogen and nitrogen is fed to a substance stream comprising the fresh gas. The constituents of the gas mixture are separated from the converter product and/or from the compressed substance mixture comprising ammonia and the fresh gas.

  • Patent number: 11427481
    Abstract: The present invention refers to the method for synthesis an absorbent material consisting of a phase of tetravalent manganese feroxyhyte (?-Fe(1-x)MnxOOH) with a negatively charged grain surface in which a percentage of iron has been isomorphically substituted by manganese atoms at 0.05-25%. Its' production is carried out in two continuous flow stirred-tank reactors arranged in serial configuration, where mild acidic conditions (pH 5-6) prevail in the first reactor and mild alkaline conditions (pH 9-10) together with high redox potential (600-700 mV) in the second reactor. The material can be used to uptake mercury, as well as other heavy metals from both water and hot gas streams. Specifically, the adsorption capacity is determined by the magnitude of the negative surface charge and the isoelectric point that can be both adjusted by the synthesis process parameters.
