One of the goals for refiners is to keep profitable margins. Low-quality crude opportunities may bring short-term satisfaction but regarding the impact on the catalyst, conclusions may be slightly different.
Diesel hydrotreating units have to meet ULSD specifications whatever type of crude oil is processed in the refinery.
Catalyst selection is a key factor to achieve the required performances: maximum ULSD production, cycle length extension and energy savings.
Low-quality crude oil and greater concentration of cracked compounds leads to more severe conditions for the catalyst.
To meet these HDS unit challenges, Axens has launched a boosted CoMo catalyst: Impulse® HR 1256.
