A system (1, 1A) for manufacturing an aromatic compound according to the present invention includes: a first manufacturing device (2) that synthesizes a target substance from natural gas; a second manufacturing device that synthesizes an aromatic compound by a catalytic reaction from the natural gas and supplies a mixed gas mainly including unreacted methane and by-product hydrogen to the first manufacturing device (2) to manufacture the target substance; and a hydrogen separation device (3, 3A) that separates hydrogen from purge gas generated from the first manufacturing device (2) and supplies the same to the second manufacturing device (4, 4A) to regenerate the catalyst used for the catalytic reaction. |
