Abstract: The invention relates to a method for transient operation of a solid oxide electrolysis cell (SOEC) stack having a cathode side and an anode side, the method comprising: supplying a flush gas comprising CO2 to said anode side; and applying a small electrolysis current of 0.001-0.05 A/cm2 active cell area, such as 0.01-0.05 A/cm2 active cell area, to the cells in the SOEC stack, for thereby generating oxygen in the anode side or for transporting to the anode side any oxygen already available in the cathode side. The method comprises also operating the SOEC stack during shut-down with a flush gas comprising CO2 on the anode side, and recycling anode product gas comprising oxygen being generated under prior normal operation of the SOEC stack, with no small current being applied. By the invention it is possible to generate small amounts of O2 to safeguard the pO2 and stability of the oxy-electrode in the anode side. The invention provides protection of not only the oxy-electrode, but also the fuel electrode in the cathode side.

Abstract: Process and plant for producing a hydrocarbon product boiling in the gasoline boiling range, comprising: upgrading a naphtha containing stream derived from Fischer-Tropsch (FT) synthesis by passing the naphtha containing stream through an aromatization stage comprising contacting the naphtha containing stream with an aluminosilicate zeolite, thereby producing said hydrocarbon product boiling in the gasoline boiling range, and a separate light hydrocarbon gas stream, such as liquid petroleum gas (LPG) stream. The synthesis gas for the FT-synthesis is produced by electrically heated reverse water gas shift (e-RWGS) of a feedstock comprising CO2 and H2.

Abstract: A system is described for providing a hydrocarbon product stream. An electrolysis section provides a syngas stream from a first feed comprising CO2 and a second feed comprising H2O, which is then passed to an F-T section where it is converted to a hydrocarbon product stream and a tail gas stream. An electrical steam reformer section said tail gas stream and convert it to a second syngas stream, which is then recycled upstream the FT section. A process is also provided for converting a first feed comprising CO2 and a second feed comprising H2O to a first hydrocarbon product stream in a system according to the invention. The system of the invention can be combined with an upgrading section, in a gas-to-liquid plant.
