What is the impact of a high diene value on the pressure drop in diesel hydrogenation reactors?
Thread Content
As the title suggests, does anyone have any experience in this regard? Could you share your thoughts on the impact that 4-5% dienes in the gasoline, accounting for 24% of the feedstock, may have on the catalyst? Thank you\ud83d\ude1c
It can cause catalyst coking. Dienes are reactive and tend to polymerize easily at high temperatures, leading to polycondensation and coking
Dienes tend to coking very easily at high temperatures; it is recommended to add a low-temperature pre-hydrogenation reactor before feeding them, so as to saturate the dienes before they proceed to subsequent processes
