Ethanol dehydration

WebDec 1, 2011 · The ethanol dehydration was performed over a commercial alumina based catalyst, which had exhibited 97.7% ethylene selectivity at 99.9% ethanol conversion during the catalyst screening experiments at temperature 400 °C. The original catalyst was in the form of cylinder with a height of 5–6 mm and a diameter of 3.6–4.0 mm. Webcial plants for ethanol production can be found elsewhere [23–26]. 2.1 Ethanol Production from Ethylene In the petrochemical industry, ethanol is produced via direct and indirect hydration of ethylene. Catalytic direct ethylene hydration was first introduced by Shell in 1947. In this process, ethanol is produced by a reversible exothermic ...

WebJun 13, 2024 · They allow ethanol to be dehydrated past 95 percent purity to nearly 99.9 percent, which is critical to meet the specifications for use as a fuel additive. Like all processes in an ethanol plant, careful attention is required in ethanol dehydration units to care for the molecular sieve (also referred to as mole sieve beads, desiccant or zeolite). WebMolecular sieve ethanol dehydration, the lower its water content, the higher quality of alcohol is produced. However, using typical multi-pressure distillation processes alone, the ethanol to water azeotopic ratio is at 95.5%, with a maximum of 97.2%. Further purification is needed to exceed the limits for a more refined final product.
