Title:
METHOD FOR PRODUCING SINGLE-RING AROMATIC HYDROCARBONS
Document Type and Number:
WIPO Patent Application WO/2012/133168
Kind Code:
A1
Abstract:
This method for producing single-ring aromatic hydrocarbons has: a breakdown/modification reaction step for obtaining a product by introducing into a breakdown/modification reaction vessel a starting material oil, contacting the starting material oil to a catalyst, and reacting the starting material oil; a purification/collection step for purifying and collecting single-ring aromatic hydrocarbons isolated from the product generated in the breakdown/modification step; a hydrogenation reaction step for hydrogenating the heavy fraction isolated from the product generated in the breakdown/modification reaction step; and a recycling step for returning the product of the heavy fraction hydrogenation reaction obtained in the hydrogenation reaction step to the breakdown/modification reaction step. In the recycling step, the product of the heavy fraction hydrogenation reaction is introduced to the breakdown/modification reaction vessel at a different position from the position of introduction of the starting material oil in a manner so that the time for the product of the heavy fraction hydrogenation reaction to contact the catalyst in the breakdown/modification reaction vessel is shorter than the time for the starting material oil to contact the catalyst in the breakdown/modification reaction vessel.
