权利人:UMICORE AG & CO KG
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:Disclosed is a direct synthesis method of nanostructured catalyst particles on surfaces of various supports. In the disclosed synthesis method of a catalyst structure having a plurality of nanostructured catalyst particles dispersed in a support by a one-step process using a high-temperature high-pressure closed reactor, the one-step process includes supplying the support and a catalyst source into the high-temperature high-pressure closed reactor; supplying an atmosphere forming gas of the reactor into the reactor; perfectly sealing the high-temperature high-pressure closed reactor and heating the reactor to produce the catalyst structure in the reactor under self-generated pressure and synthesis temperature conditions, the catalyst structure including the plurality of nanostructured catalyst particles dispersed in the support; removing internal gases of the reactor to allow the reactor to be in a high-temperature, atmospheric pressure state and supplying an inert gas into the reactor to remove unreacted materials and byproducts remaining in the reactor; and cooling the reactor to room temperature while supplying the inert gas to synthesize the catalyst structure.
