专业释义

    化學

  • 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.
    考察了反應溫度和液空時速對反應的影響,隨著液空時速的增加,低碳烯烴的選擇性有所提高,但是高於1.2h-1就不利於反應;陞溫抑制了氫轉移反應的進行,丁烷的産率下降,同時由於裂解強度的加強,乙烯和甲烷的産率皆上陞。
