SYNTHESIS GAS PRODUCTION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2019/049476
Kind Code:
A1
Abstract:
[Problem] To control the ratio between hydrogen to be produced and carbon monoxide to be produced in a synthesis gas production system. [Solution] A synthesis gas production system 1 which produces CO and H2 by means of electric reduction of an aqueous solution that contains CO2, and which comprises: an electrolysis device 6 that comprises an anode chamber 4 and a cathode chamber 5, which are divided by a diaphragm 3; a cathode-side circulation line 7 that is connected to the cathode chamber and circulates a cathode solution which contains CO2; a catalyst supply device 29 that is provided in the cathode-side circulation line and supplies a CO production catalyst to the cathode solution; and a gas composition detection device 35 that measures the ratio of H2 to CO in the produced gas which is produced in the cathode chamber. This synthesis gas production system 1 performs at least one of the control of the amount of CO production catalyst to be supplied by the catalyst supply device and the control of the voltage to be applied between an anode 15 and a cathode 16 by the electrolysis device for the purpose of keeping the ratio of H2 to CO in the produced gas within a predetermined target range on the basis of the detection result of the gas composition detection device.
