METHOD FOR PRODUCING MONOCYLIC AROMATIC HYDROCARBONS
摘要
The present method for producing monocyclic aromatic hydrocarbons is a method for producing monocyclic aromatic hydrocarbons having 6 to 8 carbon atoms. This method includes a cracking and reforming reaction step of bringing oil feedstock into contact with a catalyst to cause a reaction and obtain a product containing monocyclic aromatic hydrocarbons having 6 to 8 carbon atoms and a heavy fraction having 9 or more carbon atoms, a purification and recovery step of purifying and recovering the monocyclic aromatic hydrocarbons having 6 to 8 carbon atoms separated from the product formed by the cracking and reforming reaction step, and a first returning step of returning at least a portion of toluene obtained by the purification and recovery step to the cracking and reforming reaction step.
