[求助] 一段话翻译,异丁烯脱氢方面

论文的第四部分主要是采用CBDH-07催化剂,对不同的空速、不同的温度条件进行了探究,得出一系列数据,另外对CBDH-07催化剂的再生温度及再生性能进行了考察发现,其最佳的再生温度在400℃~450℃之间,而经过多次循环再生之后,CBDH-07的活性仍然很好,异丁烷的转化率在40%~50%之间,异丁烯的选择性在90%~94%之间,循环时间在1000 min以上。

Warning: Reference only, do not copy and use directly.

In section four of the thesis, the effects of different airspeeds and temperatures were explored to obtain a series of data when the CBDH-7 catalyst was applied. Furthermore, the regeneration temperature and the regeneration properties of CBDH-7 catalyst were also investigated, and it was found that the optimal regeneration temperature is between 400℃~450℃. After many cycles of regeneration, the catalytic activity of CBDH-7 can still maintain (retain) well. The conversion efficiencies of isobutane and isobutene are between 40%~50%, respectively, and the cycle time can exceed over 1000 min.
