Abstract: A hydrocarbon production apparatus includes a reverse shift reaction unit obtaining a synthesis gas by using carbon dioxide and hydrogen, a hydrocarbon production unit producing a hydrocarbon by using the synthesis gas, a gas-liquid separation unit separating a gas component containing hydrogen, carbon dioxide, and a light hydrocarbon and a liquid component containing a hydrocarbon from an effluent from the hydrocarbon production unit, a first separation unit separating hydrogen and carbon dioxide, and a light hydrocarbon from the gas component, and a catalytic reaction unit generating hydrogen and carbon monoxide by using the light hydrocarbon separated by the first separation unit. The reverse shift reaction unit also uses the hydrogen and carbon dioxide separated by the first separation unit. The hydrocarbon production unit also uses the hydrogen and carbon monoxide generated by the catalytic reaction unit.

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 hydrocarbon production method includes: a hydrogen extraction step of extracting hydrogen from an organic hydride by a dehydrogenation reaction; and a hydrocarbon production step of producing a hydrocarbon by a reaction by a Fischer-Tropsch (FT) process using the extracted hydrogen and carbon monoxide. In addition, in the hydrogen extraction step, reaction heat generated in the hydrocarbon production step is used.

Abstract: A method for producing p-xylene, comprising: a dimerization step of bringing a first raw material comprising isobutene into contact with a dimerization catalyst to generate C8 components comprising diisobutylene; a cyclization step of bringing a second raw material comprising the C8 components into contact with a dehydrogenation catalyst comprising Pt in the presence of hydrogen to obtain a reaction product comprising p-xylene; and a collection step of collecting p-xylene from the reaction product.
