1. method by preparing ethylene by dehydrating ethanol take the ethanol of weight percent concentration as 5~

  • 100% as raw material, is 200~

    400 ℃

    in temperature of reaction, is 0.1~

    15 hour with respect to the volume space velocity of ethanol -1Under the condition, reaction raw materials contacts with catalyzer and generates ethene;

    Wherein used catalyzer is the adhesiveless ZSM-5 molecular sieve.
