METHOD AND APPARATUS FOR HYDROGENATING HEAVY OIL

摘要

A heavy oil hydrogenating method which comprises (a) a step of introducing heavy oil into a fixed bed type reaction column packed with a hydrogenation catalyst and conducting heavy oil hydrogenation, and (b) a step of introducing the heavy oil hydrogenated in the step (a) into a suspension type reaction column packed with a hydrogenation catalyst and conducting the hydrogenation. A hydrogenation apparatus which comprises (a') a fixed bed type reaction column packed with a heavy-oil hydrogenation catalyst and (b') a suspension type reaction column packed with a heavy-oil hydrogenation catalyst for hydrogenating the heavy oil hydrogenated in the fixed bed type reaction column. The present invention can prolong the operation time of the heavy oil hydrogenation.
