Abstract:
1. A method for producing hydrocarbon compounds comprising, a) generating hydrogen gas from water in an electrolyzer b) feeding carbon dioxide gas and at least a portion of said hydrogen gas to a reverse water gas shift reactor to generate a gaseous stream including at least water steam and syngas as a mixture of hydrogen gas and carbon monoxide gas, wherein c) feeding a Fischer-Tropsch reactor with said syngas effluent from the reverse water gas reactor to generate hydrocarbon compounds, and d) a temperature of a gas in the method is changed at least near adiabatically and/or a pressure of a gas in the method is changed at least near isothermally with the temperature being increased/decreased at least near adiabatically by compressing/expanding an incoming gas in a compressor/expander with using/generating electrical energy from/to an electric power line such that involved heat energy is less than 10% of the used/generated electrical energy and the pressure is increased/decreased at least near isothermally by compressing/expanding an incoming gas in a compressor/expander with using/generating electrical energy from/to an electric power line and cooling/heating to compressed/expanded gas with delivering heat to/taking heat from a heat distribution line such that the absolute temperature ° K of the processed gas deviates less than 10% from the absolute temperature ° K of the incoming gas.
