How to improve the stability of catalyzed diesel
Thread Content
The diesel produced by our plant’s catalytic units has relatively poor stability; even after alkaline and water washing, its stability remains inadequate. I would like to ask those of you who work in similar plants how you handle this situation. Thank you for your advice
It enters the hydrogenation unit for refining.
Small plants can use solvent refining, while large plants employ hydrogenation processes.
The stability of catalytic gas is relatively poor; currently, most systems use hydrogenation refining to improve its stability.
Hydrorefining not only improves stability but also increases the cetane number. High added value. This is the common approach nowadays.
