We have provided, in the course of our reportage, clear evidence that Carbon Dioxide, as arises in a small way, relative to natural sources of emission such as volcanoes, from our varied and productive uses of Coal, can be reclaimed and productively recycled in the synthesis of hydrocarbon products, including fuels.
We once suggested that, if we US citizens of US Coal Country didn't soon wake up to that fact, we would, eventually, wind up buying tankers full of recycled Coal plant exhaust fumes from the same folks who now extort us for products made out of natural petroleum.
Herein, with another, and very similar, document soon to follow, we submit more, very clear, evidence attesting to that danger.
Comment follows excerpts from the above link to, and attached file of:
"United States Patent Application Publication Number US2010/0190874A1
Catalytic Hydrogenation of Carbon Dioxide into Syngas Mixtures
Publication date: July 29, 2010
Inventors: Agaddin Mamedov, Texas, and Abdulaziz Al-Jodai, et. al., Riyadh, Saudi Arabia
Abstract: The invention relates to a process of making a syngas mixture containing hydrogen, carbon monoxide and carbon dioxide comprising a step of contacting a gaseous feed mixture containing carbon dioxide and hydrogen with a catalyst (thus enabling) hydrogenation of carbon dioxide (and which process can be) integrated with other ... synthesis processes for making ... alcohols.
This invention relates to a catalytic process for producing a syngas mixture from carbon dioxide ... .
The object of the present invention is therefore to provide a catalyst that shows improved selectivity in reducing carbon dioxide with hydrogen into a syngas mixture, with only very little methane formation, and with good catalyst stability.
A further advantage of the process (makes it possible to vary the syngas composition so that it can be used) as a raw material in the synthesis of various other products (including) ethane, propane, ... dimethylether (and) methanol."

In other words, starting with Carbon Dioxide, we can synthesize the Diesel fuel substitute, dimethylether, DME, and, the liquid fuel and, as in ExxonMobil's "MTG"(r) process, Gasoline raw material, Methanol.
One contrary note: It is so easy to make Methane out of Carbon Dioxide, as was confirmed in 1912 by Europe's Nobel Committee in award of their Prize in Chemistry to Paul Sabatier, that these Saudi-based inventors, as in "reducing carbon dioxide with hydrogen into a syngas mixture, with only very little methane formation", deliberately worked to avoid such Methane co-production.
However, we remind you: Once we have Methane, as herein can be synthesized starting with Carbon Dioxide, we can react that Methane with even more Carbon Dioxide in "reforming" processes, such as explained more recently by Penn State University scientists - one of whom, as we documented, declared "burying CO2" as in Geologic Sequestration in leaky, nearly-depleted oil fields to be "ridiculous" - and thereby synthesize even more, and more complex, hydrocarbons.
Left unstated by the Saudis and their Texas cohorts is the source the Hydrogen which is required for this technology.
They do, though, make reference, in the full document, to the Water Gas and Reverse Water Gas Shift reactions, which can be made to produce Hydrogen; and, since Hydrogen is required in some cases in modern petroleum refineries, to upgrade natural petroleum products, we presume these OPEC operatives have that need for elemental Hydrogen covered.
But, this is only the start of it. In a dispatch to follow in coming days, as indicated above, we will disclose that these same Saudi Arabia and Texas collaborators have developed yet more technology that confirms what we have been documenting from many other sources:
Carbon Dioxide, as arises in a small way, relative to natural sources of emission, such as volcanoes, from our varied and productive uses of Coal, is a valuable raw material resource.
CO2 can be reclaimed and productively recycled into liquid and gaseous hydrocarbon fuels and chemicals.
