专业释义

    化学

  • 丁烷

    With the increase of WHSV,Light olefins selectivity increased, but WHSV above 1.2h-1 was not conducive to the reaction;Rising temperature restrain hydrogen transfer reaction,cause the decline of butane production. At the same time,ethylene production and methane production were significantly increased as a result of cracking strength.
    考察了反应温度和液空时速对反应的影响,随着液空时速的增加,低碳烯烃的选择性有所提高,但是高于1.2h-1就不利于反应;升温抑制了氢转移反应的进行,丁烷的产率下降,同时由于裂解强度的加强,乙烯和甲烷的产率皆上升。
