Abstract

This invention relates to a method of producing an aromatic hydrocarbon compound from byproducts of aromatic carboxylic acid and/or aromatic carboxylic acid alkylester preparation processes using hydroprocessing under conditions of high temperature and high hydrogen pressure in the presence of a catalyst, and to a hydroprocessing catalyst used therein.

Claims15

Dependent claims

A method of producing aromatic hydrocarbons, comprising:

a) preparing byproducts of either or both of aromatic carboxylic acid preparation processes and aromatic carboxylic acid alkylester preparation processes;
and
b) converting the byproducts into the aromatic hydrocarbons using a hydroprocessing catalyst, thus obtaining a product including the aromatic hydrocarbons.

Dependencies are inferred from the claim text.
