Abstract:
The present invention includes a method for converting renewable energy source electricity and a hydrocarbon feedstock into a liquid fuel by providing a source of renewable electrical energy in communication with a synthesis gas generation unit and an air separation unit. Oxygen from the air separation unit and a hydrocarbon feedstock is provided to the synthesis gas generation unit, thereby causing partial oxidation reactions in the synthesis gas generation unit in a process that converts the hydrocarbon feedstock into synthesis gas. The synthesis gas is then converted into a liquid fuel.

Abstract:
A process for the conversion of carbon-based material to fuel bases by a hybrid route combining direct ebullent bed liquefaction and indirect liquefaction by gasification followed by a Fischer-Tropsch synthesis, including a stage of production of hydrogen resulting from non-fossil resources and a reverse water gas reaction stage. This process makes it possible to limit emissions of greenhouse gases.

Abstract:
The invention relates to a method and installation for producing liquid energy carriers from a solid carbon carrier by means of gasifying a solid carbon carrier. The installation is at least comprised of a drying device, a gasification apparatus, a synthesizing device for synthesizing the liquid energy carrier, a device for effecting the electrolysis of water for producing oxygen serving as a gasification agent and hydrogen for the synthesis process, and of a combustion apparatus, which is connected to the output of the gasification apparatus for carbon-containing gasification residues and to the oxygen outlet of the device for effecting the electrolysis of water. According to the invention, at least a portion of the waste steam from the drying device and at least a portion of the residual gas arising during synthesis are fed to the gasification process in the gasification apparatus. In addition, the carbon-containing residuals from the gasification apparatus and a portion of the oxygen produced in the device for effecting the electrolysis of water can be fed to a combustion apparatus, and the carbon dioxide-containing and oxygen-containing waste gas from the combustion apparatus can be fed to the combustion apparatus in the form of a gasification agent.
Abstract:
A method for co-producing electric power and urea from carbonaceous fuels such as coal, by pyrolizing the coal with oxygen to produce a raw rich gas and a hot char which is gasified with air to produce a raw lean gas. Subsequent to the cleaning of the two gases, the cleaned rich gas is made up of CO and 2H2, and the clean lean gas is made up of N2+CO. The CO in the rich gas is separated from the 2H2 and is added to the lean gas to enrich it with CO to become a lean fuel gas which fuels a gas turbine and is part of a combined cycle system which efficiently generates electric power while exhausting an off-gas (flue gas) made up of N2+CO2. The 2H2 separated from the CO, and the N2+CO2 of the exhausted flue gas are together synthesized to produce urea —CO (NH2)2. To augment the 2H2 in order to make the process more efficient, steam is extracted from the power generation system, mixed with the 2H2, and electrolyzed in a high-temperature electrolysis system prior to the synthesis step with the electrical energy required for the electrolysis being derived from the combined cycle power generation source. This approach will consume the CO2 in a beneficial manner by co-producing an added-value, useful by-product while at the same time obviating the necessity of collecting CO2 and sequestering it, which is an inefficient way of mitigating the effect of global warming caused by CO2.
