对二甲苯装置吸附异构单元探讨

Xylene Isomerization Unit of Adsorbent in the Paraxylene Unit

吸附异构单元在对二甲苯装置里是最重要的单元,其中采用UOP的旋转阀技术,ADS-27,PDEB,I-300催化剂及其工艺流程,它的工艺原理,催化剂的特点都有助于我们更好的了解流程的合理性。

Adsorption of p - xylene isomerization unit in the device was the most important unit, which employed U. S. Universal Oil Products Company（UOP） rotary valve technology, ADS -27, PDEB, I -300 catalyst and process. Its process principle and the characteristics of the catalyst would help to our better understanding of the rationality of the process.
