Abstract
A device and a process for producing high purity CO by electrolysis of CO2 in a Solid Oxide Electrolysis Cell stack and a gas separation unit, also the gas separation unit may be a Solid Oxide Electrolysis Cell stack.
Claims7
A process for production of high purity CO, comprising the steps of:
- providing a first CO2 gas with a purity above 90% to a device comprising at least one Solid Oxide Electrolysis Cell and comprising a gas separation unit;
- providing a current to at least one Solid Oxide Electrolysis Cell and producing a second gas comprising CO in said Solid Oxide Electrolysis cell by means of CO2 electrolysis providing said second gas to the output gas separation unit;
- and
- operating said gas separation unit at temperatures between 0° C.-50° C., and thereby producing a third output gas comprising CO with a purity above 90%.
