HYDROGEN TREATING CATALYST OF CRACKED LIGHT OIL FRACTION

摘要

PURPOSE:To produce a pref. light oil fraction having a high cetane value, a stable hue and a low pour point and low in sulfur content by hydrogenating an aromatic nucleus contained in a catalytically cracked light oil fraction to make the same naphthenic simultaneously with deep desulfurization. CONSTITUTION:A hydrogen treating catalyst of a cracked light oil fraction contains at least one kind of a metal (A) selected from group VIB metals, at least one kind of a metal (B) selected from group VIII metals and at least one kind of a metal (C) selected from Re and Ir as active metal components. The content of the component (C) is 0.1-10wt.% with respect to (A) and (B) and the amt. of all active metals supported on a carrier.
