Reactor for carbon dioxide capture and conversion
Abstract
Disclosed herein is a multifunctional catalyst system comprising a substrate; and a catalyst pair disposed upon the substrate; wherein the catalyst pair comprises a first catalyst and a second catalyst; and wherein the first catalyst initiates or facilitates the reduction of carbon dioxide to carbon monoxide while the second catalyst initiates or facilitates the conversion of carbon monoxide to an organic compound. Disclosed herein is a method comprising reducing carbon dioxide to carbon monoxide in a first reaction catalyzed by a first catalyst; and reacting carbon monoxide with hydrogen in a second reaction catalyzed by second catalyst; wherein the first catalyst and the second catalyst are disposed upon a single substrate.

Before presenting our excerpts from the above link, we must note, prior to some extended preamble, that:
The process of the US Government-certified invention we herein disclose and report, wherein Carbon Dioxide, Methane and Water are all combined to manufacture a hydrocarbon synthesis gas suitable for catalytic condensation into liquid hydrocarbon fuels, can be made possible, and even simplified to the extreme, by one key co-reactant: Coal.
But, Coal, or any independent Carbon source, is not actually named or specified to be included in the process.

Without attempting linkage to any of our prior reports concerning the fact, we see herein that Phillips Petroleum again confirms that several known and established processes can be combined to synthesize a hydrocarbon fuel, in this case, and perhaps importantly, Methane, by recycling and reacting Carbon Dioxide, from whatever source, with hot Coal, to form Carbon Monoxide; and, then, reacting that Carbon Monoxide with Steam to form a hydrocarbon gas consisting primarily of Methane.
Such rather direct synthesis of Methane, in a process that, as a first step, recycles Carbon Dioxide through reactions with Coal, offers additional Carbon Dioxide recycling potentials, as well, as we emphasize, following excerpts from the link to:

METHOD AND APPARATUS FOR PRODUCING MIXTURES OF METHANE,CARBON MONOXIDE,AND HYDROGEN
Herein, we have yet another Coal conversion technology developed by a scientist in the employ of our local Consolidation Coal Company; but, one which generates a slightly different product mix of hydrocarbons, relative to another US Patent, issued to Consol in the same year as the subject invention of this report, and as seen in: Consol 1970 Liquid Fuels from Coal | Research & Development | News; which contains information concerning: "United States Patent 3,523,886 - Making Liquid Fuels from Coal; 1970; Inventor: Everett Gorin, et. al.; Assignee: The United States of America and Consolidation Coal Company".
Herein, another Consol scientist demonstrates that Methane can be generated as a co-product, along with a synthesis gas suitable for catalytic condensation into liquid hydrocarbon fuels, by, in a way similar to other Coal conversion technologies we have reported to you, reacting hot Coal with Steam.

We have many times made reference to, and report of, the potentials for utilizing biological agents for the large-scale recycling of industrial effluent Carbon Dioxide.
Although we are personally and preferentially drawn to more straightforward chemical processes for CO2 recycling, such as those technologies based on the Sabatier process, and on CO2 reforming with Methane and/or Steam, we have documented that Algae can be employed to harvest industrial exhaust gas Carbon Dioxide, and to transform it into a wider variety of products, including "lipids", which can then rather easily be refined into Diesel fuel.
