Discussion on the reasons for frequent deactivation of MTBE ion filter catalysts!
Thread Content
Raw material conditions: 1. Catalytic liquefied gas fed directly into the system; 2. The catalytic liquefied gas contains about 1000 PPM of water; 3. Sulfur content ≤ 25. Analysis of the cause: Water is present in the liquefied gas； It could also be that the catalytic liquefied gas fails the washing test; the liquefied gas contains alkali, which gives it an alkaline nature, and this leads to a neutralization reaction with the resin catalyst, resulting in the deactivation of the catalyst. Dear experts, if you have any good suggestions, please feel free to leave comments!
Is it because substances such as water contained in liquefied gas are alkaline? General resin catalysts are sensitive to alkaline substances
The last edit to this post was made by Green Lotus on 2019-4-2 at 09:59, to determine what impurities in the feed components are responsible for catalyst deactivation
It is caused by excessive water content; enhance dehydration.
Enhance washing and control the raw materials well!
The raw material contains basic ions, so the upstream equipment enhances washing and water removal.
It is highly recommended to rinse the unit immediately; alkaline substances can cause fatal damage to the catalyst. I’ve experienced this firsthand: lol
A common problem is the presence of alkali in liquefied gas; simply carrying out liquid removal treatment will solve it, and it’s advisable to install adsorption equipment as a precaution. This way, one can take a break at the office.

It is recommended to enhance the water replacement in the washing system of the liquefied gas desulfurization and denaturation system, and to conduct data analysis on the catalyst so that appropriate measures can be taken. Generally, the pH value of the liquefied gas washing system is alkaline, which has a significant impact on the catalyst’s activity.
