Abstract
Method for producing monocyclic aromatic hydrocarbons includes a cracking and reforming reaction step of obtaining products containing monocyclic aromatic hydrocarbons having 6 to 8 carbon atoms and a heavy fraction having 9 or more carbon atoms by bringing the feedstock oil into contact with a catalyst for producing monocyclic aromatic hydrocarbons containing crystalline aluminosilicate to cause a reaction, a catalyst separation step of separating and removing the catalyst for producing monocyclic aromatic hydrocarbons together with tricyclic aromatic hydrocarbons contained in the products from a mixture of the products and a small amount of the catalyst for producing monocyclic aromatic hydrocarbons carried by the products, both of which are derived in the cracking and reforming reaction step, and a purification and recovery step of purifying and recovering the monocyclic aromatic hydrocarbons having 6 to 8 carbon atoms which are separated from the products formed in the cracking and reforming reaction step.
