Abstract: A hydrocarbon production apparatus includes a synthesis gas production unit structured to produce a synthesis gas containing carbon monoxide and hydrogen by using carbon dioxide and hydrogen, a hydrocarbon production unit structured to produce a hydrocarbon by using the synthesis gas, and a first separator structured to separate a recycle gas containing a light hydrocarbon having 4 or less carbon atoms from an effluent from the hydrocarbon production unit. The synthesis gas production unit is structured to receive supply of the recycle gas and also use the recycle gas for production of the synthesis gas.

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.
