    Abstract: 本發明係關於一種藉由在固態氧化物電解池(solid oxide electrolysis cell,SOEC)中產生之CO的膜純化製備高純度一氧化碳(CO)之方法,其包含以下步驟:藉由CO2之SOEC電解生成CO與CO2之氣體混合物,經由壓縮器或噴射器施加適度壓力於一或多個連接至該SOEC之出口之膜單元中的膜之滯留側上,將比該適度壓力低的壓力施加於該膜之滲透側上,將現在富含CO之滯留物流分成兩個單獨的部分,使該滯留物流之第一部分膨脹以達到滲透低壓條件,引導該滯留物之上述部分至該膜之滲透側以降低此側上的CO2之分壓,及再循環出口滲透物流返回至該SOEC與新製CO2一起作為饋入氣體。 該膜單元較佳地經設計成具有管狀膜或多個串聯連接的平面膜,且該滯留物流與該滲透物流以逆流模式運行。

    Abstract: A synthetic, layered, crystalline aluminosilicate. The aluminosilicate has the general formula (expressed as moles of oxide ratios): (M2/nO)x: (SiO2)y: (Al2O3)z wherein M represents one or more n-valent cations selected from sodium, potassium and other cations capable of replacing sodium or potassium by ion-exchange. The ratio y/z is between 15 and 300. The ratio x/z is determined from the criterion of electron neutrality between anions and cations, and wherein the structural aluminum is tetrahedrally coordinated in the crystal lattice of the above formula. The aluminosilicates of the invention are used as catalysts for the preparation of higher hydrocarbons from raw material containing olefins or oxygenates. The aluminosilicates are prepared from a synthesis mixture comprising the following compounds and molar ratios: SiO2/Al2O3: 5-500; M2/nO/SiO2: 0.1-10; OH/SiO2: 0.1-5; and H2O/SiO2: 5-200. The synthesis mixture is maintained under autogenous pressure at a temperature of 80 DEG -270 DEG C. for four hours to 100 days.

    Abstract: Ammonia converter for radial flow through two catalyst beds has a central heat exchanger mounted centrally in one of the beds. The process stream of synthesis gas is obtained by combining inside the converter separate feed streams: a shell stream serving to cool the converter shell, an exchange stream serving to cool the central heat exchanger, and a by-pass stream for final adjustment of the temperature of the process stream. The process stream passes in succession radially through the first catalyst bed in inwards direction through the central heat exchanger for being cooled, and radially through the second catalyst bed.
