MANUFACTURING METHOD OF AROMATIC HYDROCARBON FOR VARIOUS USES FROM BY-PRODUCTS OF AN AROMATIC CARBOXYLIC ACID AND/OR AROMATIC CARBOXYLIC ALKYL ESTER MANUFACTURING PROCESS

摘要

PURPOSE: A manufacturing method of aromatic hydrocarbon is provided to manufacture an aromatic hydrocarbon compound by a hydrogenation treatment reaction of a by-product which is generated from an aromatic carboxylic acid and/or aromatic carboxylic alkyl ester manufacturing process, under the hydrogen pressure in high temperature and high pressure.;CONSTITUTION: A manufacturing method of an aromatic hydrocarbon comprises: a step of preparing by-products which is generated by manufacturing processes of aromatic carboxylic acid and/or aromatic carboxylic acid alkyl ester; a step of converting the by-products to aromatic hydrocarbon under the presence of a hydrogenation catalyst, and obtaining a product including aromatic hydrocarbon; and a step of separating the product into liquid aromatic hydrocarbon, gas components, and water. The by-products comprise an aromatic compound which contains a substituent with hydrocarbon or oxygen in a benzene ring.;COPYRIGHT KIPO 2013;[Reference numerals] (AA) Reactor; (BB) Gas/liquid, oil, and water separation
