Document Type and Number:
Japanese Patent JP7222034
Kind Code:
B2
Abstract:
An object is to reduce an overall cost including the construction cost of a plant and its raw material and energy costs, and also reduce carbon dioxide emissions. An aromatic compound manufacturing method is characterized in that the method comprises: a step A of manufacturing an aromatic compound mixture from a raw material mixture gas containing carbon dioxide or carbon monoxide or both of these and hydrogen; a step B of manufacturing an aromatic compound mixture by a cracked petroleum-derived BTX manufacturing process, a reformate-derived BTX manufacturing process, and a synthetic BTX manufacturing process using naphtha as a raw material; a step C of combining the aromatic compound mixture manufactured in the step A and the aromatic compound mixture manufactured in the step B; and a step D of separating a desired aromatic compound from the aromatic compound mixture combined in the step C and purifying the desired aromatic compound.
