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 这种新型的沸石配入催化裂化催化剂后,使异构化和裂化反应之间的平衡向异构化方向移动。因此,催化裂化石脑油的长链组分会支化而不是断裂。结果是汽油辛烷值增加而汽油转化成液化石油气的量最少。查看更多
