摘要:The invention provides methods for a one-pot synthesis of molecular sieves of the CHA-type. The method uses molecular and non-molecular sieves as sources of silicon and aluminum. A first OSDA is selected from tetraethylenepentamine (TEPA) and triethy-lenepentamine (TETA). The synthesis mixture comprises a first metal selected from copper, iron and zinc. Optionally, the synthesis mixture may furthermore comprise a second OSDA and/or a second metal selected from manganese, cesium, magnesium, calcium, strontium, barium, yttrium, titanium, zirconium, niobium, iron, zinc, silver, lanthanum, cerium, praseodymium, neodymium, promethium, samarium, europium, gadolinium, terbium, dysprosium, holmium, erbium, thulium, ytterbium, lutetium and mixtures thereof. The molecular sieves of the CHA-type obtainable by the method can be used as SCR-catalytically active substances for the removal of nitrogen oxides from exhaust gases of combustion engines.

摘要:The present application relates to the technical field of chemical production, and particularly relates to a molten iron catalyst for high-temperature Fischer-Tropsch synthesis, a preparation method of the molten iron catalyst and an application of the molten iron catalyst in preparation of high-carbon α-olefin from synthesis gas. The molten iron catalyst comprises iron oxides and a cocatalyst, and mass contents of components are: potassium oxide per 0.1-1 g/100gFe; strontium oxide 0.1-1 g/100gFe; manganese oxide 1-20 g/100gFe, and rare earth metal oxides 1-10 g/100gFe; the rest is iron oxides. The molar ratio of ferric iron to double ferrous iron in the iron oxides, namely Fe3+/2Fe2+, is 0.4-1.5. The application aims to provide a molten iron catalyst with high strength, high activity, and high selectivity of higher α-olefin.
