專業(yè)釋義

化學(xué)

• 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(yīng)溫度和液空時(shí)速對(duì)反應(yīng)的影響,隨著液空時(shí)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(yīng);陞溫抑制了氫轉(zhuǎn)移反應(yīng)的進(jìn)行,丁烷的産率下降,同時(shí)由於裂解強(qiáng)度的加強(qiáng),乙烯和甲烷的産率皆上陞。
