Beschreibung
Zusammenfassung:	Disclosed herein is a two-step process for preparing ultra low sulfur diesel fuel having improved properties and sulfur content of 10ppm or less, comprising deep hydrodesulfurization followed by hydrotreatment, wherein the recombination of sulfur causing the increase in sulfur content upon the hydrotreatment is effectively suppressed. According to the present invention, color improvement and ultra deep desulfurization effects can be simultaneously realized while maximally utilizing the already existing equipments, thus generating economic benefits.
