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:An organic synthesis of materials to achieve removal of low molecular weight ionic species, such as transition metal ions including cobalt, iron, nickel, and zinc, from aqueous solutions. The synthesis includes the steps of providing a cation exchange resin, functionalizing the cation exchange resin using a chloride intermediate to form a sulfonyl chloride resin, and reacting a multi-amine based ligand with the sulfonyl chloride resin to form a sequestration resin. The synthesis further includes the steps of cooling the sequestration resin, and washing and drying the sequestration resin.

摘要:The method of preparing a silver catalyst for synthesis of formaldehyde by oxidizing methyl alcohol which consists in that a carrier is impregnated with an aqueous or an aqueous-alcohol solution containing complex ions of silver having the general formula [Ag(X) n ] + or [Ag(Y) 2 ] - , where X is ammonia, ethylenediamine, triethylenetetramine or triaminotriethylamine, Y is a thiocyanate, cyanide, acetate, or hydroxyl ion, and n is 1 or 2. The impregnated carrier is processed, at a temperature of from 10° - 100°C, with a reducing agent taken in the quantity sufficient to reduce the silver completely from said ion. The thus-prepared catalyst is dried at a temperature of from 80° to 400°C. It is recommended that the catalyst be washed with water before drying. The thus-prepared catalyst has a highly developed active surface with a small content of silver (the specific surface of the catalyst is 0.7 - 7 square meters per gram, with the metal silver content of the catalyst being from 5 - 10 per cent by weight). The catalyst is highly active and has good selectivity in the process of formaldehyde synthesis from methyl alcohol. The yield of formaldehyde with the proposed catalyst is from 75 - 80 per cent, calculating with reference to the passed methyl alcohol, with the selectivity of the process being from 89 - 95 per cent.
