Benefits of technology

The invention improves the conversion of carbon to liquid fuel products in a coal-to-liquid hydrocarbon production process by modifying the process or incorporating a water-splitting process. This reduces the amount of carbon-based pollutants produced by the process. The water-splitting process produces hydrogen, which can be used in the production of synthesis gas or can be recycled to a gasification process. The recycling of tail gases from a Fischer-Tropsch process or the reaction of carbon dioxide with tail gases can also improve the yield of liquid fuel products and reduce the production of carbon-containing pollutants. Overall, the invention enhances the efficiency and reduces the environmental impact of liquid fuel production.

Problems solved by technology

The use of a nuclear power source to produce electricity or power to supply to the water-splitting process decreases the production of pollutants associated with conventional coal-fired electricity generation operations.

Embodiment Construction

[0053]According to embodiments of the invention, a nuclear power source may be integrated with or incorporated into a liquid fuel production process, such as a coal-to-liquid hydrocarbon production process, to facilitate the production of hydrocarbons and liquid fuel products from coal. Although the additional heat produced by a nuclear power source may not be needed in a conventional coal-to-liquid hydrocarbon production process, the integration of a nuclear power source with a coal-to-liquid hydrocarbon production process, or other liquid fuel production process, facilitates the use of alternative processes to produce oxygen (O2) and hydrogen (H2), allowing expensive equipment to be removed from a liquid fuel production process.

[0054]While various embodiments of the invention may be integrated with liquid fuel production processes, many of the embodiments will be described with respect to a coal-to-liquid hydrocarbon production process. It is understood that other liquid fuel prod...

Abstract

Carbon-containing tail gases and pollutants in a coal-to-liquid hydrocarbon production process, or other liquid fuel production process, may be reacted to produce additional synthesis gas which may be used to produce liquid fuels and hydrocarbons or which may be recycled within the liquid fuel production process to improve conversion of carbon to liquid fuels or hydrocarbons.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application is a continuation-in-part application of U.S. patent application Ser. No. 11 / 552,604 filed on Oct. 25, 2006, and entitled “SYNTHETIC FUEL PRODUCTION USING COAL AND NUCLEAR ENERGY,” the disclosure of which is incorporated herein by reference in its entirety.GOVERNMENT RIGHTS[0002]The United States Government has certain rights in this invention pursuant to Contract No. DE-AC07-05-ID14517 between the United States Department of Energy and Battelle Energy Alliance, LLC.BACKGROUND OF THE INVENTION[0003]1.
