    • A distillation process for the production of dehydrated ethanol from dilute aqueous solutions of ethanol characterized in that the distillation is performed in a two-column system wherein the first column--for rectification--is operated under such a pressure that the second column--for dehydration--is heated exclusively with the vapors of the first column; in the first column the concentration of the dilute aqueous ethanol is effected to an ethanol concentration below the composition of the binary ethanol-water azeotrope; the separation of water is effected from the lower layer of the condensed head product of the second column; the separation of impurities and entrainers, having a lower boiling point than ethanol, is effected at the head of the first column and that of impurities, having a higher boiling point, above the feed point of the dilute aqueous solution in the first column; and, in the second column, the dehydration is effected by means of entrainers, with the addition of a fuel component or fuel, to which the ethanol is to be added, if required, while separating the aqueous phase as a head product.
    • 用于从稀乙醇水溶液中生产脱水乙醇的蒸馏方法,其特征在于,蒸馏是在双塔系统中进行的,其中第一列用于精馏 - 在第二塔 - 在脱水 - 仅用第一列的蒸气加热; 在第一列中,稀乙醇水溶液的浓度达到低于二元乙醇 - 水共沸物组成的乙醇浓度; 水的分离是从第二塔的冷凝头产物的下层进行的; 具有比乙醇沸点低的杂质和夹带剂的分离在第一塔的头部和高沸点的杂质高于第一塔中的稀水溶液的进料点进行; 并且在第二列中,如果需要,在分离水相作为头部产物的同时,借助于夹带剂进行脱水,同时加入添加有乙醇的燃料成分或燃料。

    • A method for producing a catalyst comprising phosphoric acid and a carrier, for the hydration of olefins with 2-3 carbon atoms to the corresponding alcohols, the method comprising:contacting a clay, containing essentially montmorillonite, contaminated by no more than 3% accompanying minerals and containing up to 0.5% by weight K.sub.2 O, or a mineral of the montmorillonite group, containing no potassium, but having the montmorillonite crystalline lattice, with an acid until it has an Al.sub.2 O.sub.3 content of 13-18% by weight and a surface area of 200-400 m.sup.2 /g;admixing the so-treated clay with 5-15% by weight, based on the total dry admixture, of one or more oxides of metals of Group VI of the Periodic System;adjusting the water content of the admixture to 20-35% by weight;pressing the admixture into a desired shape and calcining at 500.degree.-800.degree. C.;treating the so-formed carrier material with an acid until it has an Al.sub.2 O.sub.3 content of 1-5% by weight and a specific surface area of 150-250 m.sup.2 /g; andthen impregnating the resulting carrier with phosphoric acid; and the catalysts so-produced are disclosed.
