Abstract: A method for producing xylene, including a conversion reaction step of bringing a raw material containing a light hydrocarbon having 2 to 7 carbon atoms as a main component into contact with a crystalline aluminosilicate-containing catalyst to produce a product containing a monocyclic aromatic hydrocarbon having 6 to 8 carbon atoms and a xylene conversion step of subjecting the product to a disproportionation reaction or a transalkylation reaction.

Abstract: A method for producing a monocyclic aromatic hydrocarbon having 6 to 8 carbon atoms, including bringing a raw material which contains a light hydrocarbon having 2 to 7 carbon atoms as a main component into contact with a catalyst composition for producing a monocyclic aromatic hydrocarbon having 6 to 8 carbon atoms. The catalyst composition for producing a monocyclic aromatic hydrocarbon having 6 to 8 carbon atoms is coated with an amorphous silicon oxide compound and contains a crystalline aluminosilicate, and the silicon oxide compound is a silicon oxide compound derived from a compound represented by XnSi(OR)4-n, where X represents a hydrogen atom or an alkyl group, R represents an alkyl group, and n represents an integer of 0 to 4.
