ThedehydrationofmethanoltoDMEisagasphasereactionalsocatalyzedbyacids.Theconversionand...
The dehydration of methanol to DME is a gas phase reaction
also catalyzed by acids. The conversion and selectivity to DME at
different temperatures are shown in Fig. 16 for three weight hourly
space velocities (WHSVs) for the 20 wt% encapsulated sample.
Conversion is given after 30 reaction minutes, no deactivation of
the catalyst was observed during the experiments.
At WHSV = 2 h1 methanol conversion levels of 70% and very
low DME selectivities are achieved over the whole temperature
range. When increasing the WHSV (4 h1) both selectivity and conversion
increase with temperature. At the highest WHSV (8 h1)
conversion is the lowest, but at the highest temperature the selectivity
is the highest. 展开

不同的温度,如图16所示为三重量每小时
空间速度(whsvs)为20重量%封装样品。
转换后30分钟没有反应,失活
该催化剂是在观察实验。
在空速=2小时1甲醇转化水平的70%和
二甲醚选择性低,实现对整个温度
范围。当越来越多的空速(4小时1)选择性和转换
随温度的增加。在最高空速(8小时1)
转换是最低的,但在最高温度选择性
是最高的。

追问
这种不通顺的译文,拿谷歌也可以做出,我又何必来此提问
追答
那请问你为什么还要问这种问题呢?
