    • The disclosure relates to a process for making C.sub.2 to C.sub.4 -olefins from gas mixtures containing methanol, dimethylether and optionally steam in the presence of catalysts at temperatures of 250.degree. to 500.degree. C. under pressure of 0.1 to 6 bars, unreacted feed material being recycled. To this end, the disclosure provides for a mixture containing methanol and water in a ratio by volume of 1:(0 up to 2) to be evaporated and reacted in a reactor having the catalyst placed therein; for the reaction gases to be partially condensed by cooling them and separated, in a separator, into three phases; for the oil phase consisting of higher aliphates and aromates to be removed and for the remaining aqueous phase and gas phase to be water-scrubbed in a scrubbing column under pressures of 1 to 40 bars; for a gaseous hydrocarbon mixture containing predominantly C.sub.2 to C.sub.4 -olefins to be removed overhead and separated into its components; for an aqueous phase containing unreacted methanol and intermediarily formed dimethylether to be removed from the base portion of the scrubbing column; for the methanol and dimethylether to be distilled off in a stripping column and recycled into the reactor; and for the water to be removed from the base portion of the stripping column.
    • 本公开涉及一种在0.005至500℃的温度下,在0.1至6巴的压力下,在催化剂存在下,在甲醇,二甲醚和任选蒸汽的气体混合物中制备C 2至C 4烯烃的方法,未反应的原料为 回收。 为此,本公开内容提供了以1:(0至2)的体积比的甲醇和水的混合物进行蒸发并在其中放置有催化剂的反应器中反应; 反应气体通过冷却而被部分冷凝,并在分离器中分离成三相; 用于由更高的脂肪族和芳烃被除去的油相和剩余的水相和气相在1至40巴的压力下在洗涤塔中进行水洗; 对于主要含有C2至C4-烯烃的气态烃混合物,其顶部除去并分离成其组分; 对于含有未反应的甲醇和中间形成的二甲醚的水相从洗涤塔的基部除去; 甲醇和二甲基醚在汽提塔中蒸馏除去,再循环到反应器中; 并且用于从汽提塔的基部除去水。

    • A carrier-supported catalyst is made by applying one or more non-noble metal and noble metal components on to a ceramic honeycomb structure coated with a layer of a heat-resistant metal oxide. To this end, the ceramic honeycomb structure is dipped at least once into an aqueous suspension of pseudoboehmite and zirconium oxide hydrate, the honeycomb structure so treated is dried at temperatures of up to 250.degree. C. and calcined at temperatures of up to 1000.degree. C.; next, the honeycomb structure is impregnated with an aqueous solution of at least one iron salt, and, if desired, nickel and cerium salts, dried at temperatures of up to 250.degree. C. and annealed at temperatures of up to 600.degree. C.; next, the honeycomb structure is impregnated with an aqueous solution containing at least one soluble compound of platinum, rhodium or palladium, and, if desired cerium, one of the solutions under (b) or (c) being required to contain cerium; the honeycomb structure so treated is ultimately dried at temperatures of up to 250.degree. C. and annealed at temperatures of up to 600.degree. C.
