钢管的腐蚀穿孔则是由于燃煤中含较多硫或硫的化合物，在燃烧过程中产生高温熔融盐，加速基体铁的氧化腐蚀造成的。

However, the melting salt developed during combustion of the sulphur rich coal accelerates the oxidative corrosion of the iron matrix and hence results in penetration of the tube.

然后，再生的吸附剂用于脱除另外的硫氧化化合物。

The regenerated adsorbent is then used to remove additional sulfur-oxidated compounds.

So I show that here, so in green, you have what's called a carboxcylic acid group, a c o o h, which gets converted by s o c l 2 to a c double bond o c l or an acid chloride.

我在这里用绿色表示，我们所说的羧酸族化合物，碳，氧，氧，氢，它被亚硫酰氯转化为,一个碳氧双键与碳氯单键组成的酰氯。
