Title:
METHOD FOR PRODUCING MONOCYCLIC AROMATIC HYDROCARBON
Document Type and Number:
WIPO Patent Application WO/2011/118753
Kind Code:
A1
Abstract:
Disclosed is a method for producing a monocyclic aromatic hydrocarbon, wherein a monocyclic aromatic hydrocarbon having 6-8 carbon atoms is produced from a starting material oil that has a 10 volume percent distillation temperature of 140°C or more and a 90 volume percent distillation temperature of 380°C or less. The method for producing a monocyclic aromatic hydrocarbon comprises: a decomposition and reforming reaction step wherein a product that contains a monocyclic aromatic hydrocarbon having 6-8 carbon atoms is obtained from the starting material oil; a refining and collection step wherein the monocyclic aromatic hydrocarbon having 6-8 carbon atoms separated from the above-mentioned product is refined and collected; a hydrogenation reaction step wherein a heavy distillate fraction separated from the above-mentioned product and having 9 or more carbon atoms is hydrogenated; and a recycling step wherein the hydrogenation reaction product of the heavy distillate fraction obtained in the hydrogenation reaction step is returned to the decomposition and reforming reaction step.
