请教这一句应该如何翻译? 主要是关于Bioethers,是以ETBE作为调和组分加入 汽油 里面 With a slight investment/revamp, existing MTBE units can start producing ETBE. These ETBE units have been using dry ethanol with 0.1% water 。As ETBE kinetics are still favourable from an industry perspective, the conversions/yields are good even with wet recycle ethanol. If one can meet the TBA (tertiary butyl alcohol)specification in ETBE, there is no significant obstacle preventing the revamping of existing MTBE units. 这是上一段,发的是下一段的开头。开头之后剩下的就很好理解了。查看更多6个回答 . 3人已关注
