REFINED OIL AND PROCESS FOR PRODUCING THE SAME

摘要

A process for producing a refined oil which comprises contacting a feed oil with hydrogen in the presence of a demetallization/desulfurization catalyst (3) and a hydrogenolysis catalyst (5) to thereby obtain a refined oil which has a viscosity at 135 DEG C of 20 cSt or lower, a pour point of 30 DEG C or lower, an alkali metal concentration of 1 wt.ppm or lower, a vanadium concentration of 10 wt.ppm or lower, and a sulfur concentration of 0.3 wt.% or lower. Thus, a refined oil sufficiently reduced in viscosity, pour point, and sulfur concentration can be produced at low cost.
