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。

N-UNCOUNT Butane is a gas that is obtained from petroleum and is used as a fuel. 丁烷
Therefore, it is necessary to extend the resource of isobutene by dehydrogenation of butanes.
因此，通过异丁烷脱氢扩大异丁烯的来源是必要的。
Butanes and butenes can be maintained in the liquid states at ambient temperature under quite moderate pressure.
在适当的大气压力及常温下，丁烷和丁烯均可保持液体状态。
A field gas processing plant typically removes varying amounts of ethane, propane, butanes, and heavier hydrocarbon liquids from the gas stream.
气田加工厂一般会从气流中脱除不同数量的乙烷、丙烷、丁烷以及较重的烃液。
