"Первый вопрос,重整反应循环氢中S Cl含量一般都在多少",

"Если вы не против,顺便问一下水氯平衡的作用"

"Обычно измеряют содержание HHCl和HH和S和的含量，没有单独测S和CI和，HCl不超过5，H和S 1-就可以"

"Первый вопрос，一般用检测管检测的话HCl约为5~8ppm和硫化氢一般为0.8~ppm。化验的家伙分析结果里面一般只有硫化氢值一般为ppm。第二个问题重整催化剂是双功能催化剂。一般通过注水或注氯来保持催化剂上的水氯平衡（氯含量一般为催化剂质量的1.1%-到.3%）。金属功能和酸性功能共同作用使原料发生芳构化反应。金属性强催化剂加氢脱氢功能强但是容易引起积碳使芳烃转化率下降。而酸性功能强容易发生加氢裂化反应使重整循环氢纯度降低液收下降芳烃收率下降因此维持催化剂水氯平衡对生产来说十分重要"

"Бasically согласен с четвёртым мнением循环氢中HCL和H和S量根据选用的催化剂和进料杂质含量不同会略有些差别"

"Согласен с четвёртым基本有时按进料组分略微调整"
