Problems solved by technology

Additionally, the excess steam required by the SMR can significantly reduce overall plant fuel efficiency and / or thermal efficiency
Additionally, the hydrogen / carbon monoxide molar ratio in the SMR product syngas may not be suitable for downstream processes such as FT synthesis
In addition, the conversion of carbon dioxide may be too low to be acceptable

Embodiment 1

[0159] Example 1: NiDFB test

[0160] The operation test of nickel DFB was carried out to verify its effectiveness for dry reforming of methane and carbon dioxide to produce synthesis gas. Even in the presence of trace pollutants, such as sulfur, the dry reforming of carbon dioxide and methane is achieved. In Table 2, AR refers to the burner / regenerator 235 of NiDFB 200, and FR refers to its reformer / regulator 210. The preferred gas includes tail gas and synthesis gas, and the alternative gas includes tail gas, carbon dioxide and water, and CH 4 Rich 5 gas contains methane and carbon dioxide.

Abstract

A system for the production of synthetic fuel, the system including a catalytic dual fluidized bed (DFB) configured to produce, from a DFB feedgas, a DFB product containing synthesis gas; and a Fischer-Tropsch (FT) synthesis apparatus fluidly connected with the catalytic DFB, wherein the FT synthesis apparatus includes an FT synthesis reactor configured to produce, from an FT feedgas, an FT overhead and a liquid FT product containing FT wax, wherein the FT feedgas contains at least a portion of the DFB product; and a product separator downstream of and fluidly connected with the FT synthesis reactor, wherein the product separator is configured to separate, from the FT overhead, an FT tailgas and an LFTL product containing LFTL. A method of producing synthetic fuel is also provided.

Description

[0001] Statement regarding research or development funded by the federal government [0002] Not applicable. Technical field [0003] The present invention generally relates to the production of synthetic hydrocarbons. More specifically, the present invention relates to the production of synthetic hydrocarbons via Fischer-Tropsch conversion of synthetic gas. Further more specifically, the present invention relates to the production of synthetic hydrocarbons via the Fischer-Tropsch conversion of synthesis gas, at least a portion of which is produced via a catalytic double fluidized bed. Background technique [0004] In the context of its broadest general application, the term "gasification" has been commonly used to describe the conversion of solid, liquid, or vaporized hydrocarbons, or more heterogeneous but mainly carbonaceous compounds, into synthesis gas (also Any process called syngas (syngas). Synthesis gas usually consists of a gas mixture consisting mainly of carbon monoxi...
