How can phosphorus in hydrogenation feedstocks be removed?
Thread Content
As the title suggests, it has been determined that our hydrogenation feed contains approximately 350 ppm of phosphorus. If this phosphorus is not removed, it will cause catalyst poisoning. I would like to ask everyone what methods can be used to remove phosphorus. The phosphides in our oil are mainly phosphate esters, phenol phosphate esters, alkyl phosphate esters, alkyl thiophosphate ester amine salts, and the like.
This issue doesn’t seem too easy. I’ll try to figure it out on my own; I hope experienced colleagues can offer some guidance. Additionally, I’ve read that phosphides can be used as hydrogenation catalysts. I wonder if the phosphorus in our raw materials can be converted into a form that is beneficial for hydrogenation
It is recommended to first figure out the origin of phosphorus, addressing the issue at its source; for example, whether the high-temperature corrosion inhibitor contains phosphorus or not.
