/ A method for producing aromatic hydrocarbon from byproducts of aromatic carboxylic acids and/or their alkyl esters preparation processes

摘要

The present invention relates to a process for producing an aromatic hydrocarbon compound through hydrotreating reaction with a hydrogen pressure at a high temperature and a high pressure in a process of producing an aromatic carboxylic acid and / or an aromatic carboxylic acid alkyl ester, and a hydrotreating catalyst used therefor.
