The utility model relates to an aromatic PSA (Pressure Swing Adsorption) hydrogen production device capable of improving yield. The device comprises a catalytic device, an ethylbenzene device and an aromatic PSA device, a dry gas pipeline for conveying dry gas into the ethylbenzene device is arranged on the catalytic device; the ethylbenzene device comprises an alkylation reactor and a tail gas absorption tower, an inlet of the alkylation reactor is connected with a dry gas pipeline, an outlet of the alkylation reactor is provided with a tail gas pipeline connected with the tail gas absorption tower, and an outlet of the tail gas absorption tower is provided with a gas conveying pipeline for conveying tail gas to the aromatic PSA device. Dry gas in the catalytic device enters the aromatic PSA device through the ethylbenzene device to be purified, and the amount of obtained hydrogen is obviously increased compared with the amount of hydrogen generated when the dry gas in the catalytic device is conveyed into t
