HYDROGENATION METHOD AND APPARATUS FOR PHTHALATE COMPOUND

摘要

The present invention relates to a hydrogenation method and apparatus for a phthalate compound. The hydrogenation method and apparatus of the present invention can increase the entire catalyst lifespan through operation after dividing an area which has different catalyst activity, during a hydrogenation reaction process of a phthalate compound. Accordingly, it is possible to increase productivity since process maintenance and repair costs are reduced, and process stability is increased.
