WIPO Patent Application WO/2020/091437

A1

A hydrofinishing catalyst according to the present invention comprises: an amorphous silica-alumina support; and a hydrogenated active metal supported on the support, and has an Al composition having a total mass (wt%) of Al and Si as a denominator and a mass (wt%) of Al as a numerator, wherein with respect to a reference line, which is a straight line passing through the center of a cross-section of the support, locations evenly spaced apart along the reference line are sequentially numbered, wherein composition uniformity, which is defined as UN by the Al composition at the i-th location and an average Al composition at the cross-section of the support passing through the center of the support, is 3.0 or less.
