Abstract
Conditions selected for lubricant base oil production can be used to also produce a high quality diesel product. The diesel product can have a cetane index or cetane number of at least 55, corresponding to a high value diesel fuel. The diesel product can also have good cold flow properties, such as a pour point of −40° C. or less and/or a cloud point of −25° C. or less. Additionally, the sulfur content of the diesel product can be low, such as less than 1 wppm. This can allow the diesel product to be blended with other potential diesel boiling range products that have a higher sulfur content while still meeting an overall diesel fuel specification. The aromatics content can also be low, allowing the premium diesel to comply with various regulatory requirements.
