翻译练习(一)? the new zeolite, when formulated into an fcc catalyst, shifts the balance between isomerization and cracking toward the isomerization. what you see, therefore, is branching of the longer-chain fcc naphtha components, as opposed to cracking. the result is increased octane with minimal conversion of gasoline to lpg 这种新型沸石加入到催化裂化催化剂中,使异构化和裂化反应间的平衡向异构化方向进行。因此,新型沸石是催化裂化石脑油的长链化反应的一个分支,用于抑制裂化反应。其作用是增加辛烷含量,使汽油最小程度的转化为液化石油气。查看更多
