CO2 Hydrogenation over Copper-Based Hybrid Catalysts for the Synthesis of Oxygenates - Utilization of Greenhouse Gases - ACS .
We have earlier reported on Korea's achievements in the recycling of Carbon Dioxide.
Herein, we submit a publication from Korean scientists detailing some specifics on improving the conversion of Carbon Dioxide, as we have many times documented to be feasible, into the liquid fuels, and Gasoline and plastics synthesis raw materials, Methanol and Di-Methyl Ether (DME).
This submission is only prelude to a document we find far more interesting, issued prior to this publication, which we will, in a separate dispatch to follow in coming days, report.
For now, we present, with comment appended, excerpts from:
"CO2 Hydrogenation over ... Hybrid Catalysts for the Synthesis of Oxygenates

Abstract: Hybrid catalysts consisting of Cu-based methanol synthesis catalyst and zeolite were investigated for CO2 hydrogenation by following the idea that thermodynamic limitation in methanol synthesis from CO2 hydrogenation could be overcome through in situ transformation of methanol to dimethylether(DME) to enhance the yield of oxygenates (methanol + DME). Cu/ZnO/ZrO2 and Cu/ZnO/Ga2O3 were chosen as methanol synthesis catalysts, and NaZSM-5, HZSM-5, H-Ga-silicate and SAPO-34 as zeolites. The hybrid catalyst of Cu/ZnO/ZrO2 and H-Ga-silicate showed the highest yield of oxygenates. The modification of reducibility or oxygen coverage due to the interactions between methanol synthesis catalyst and zeolite was found to improve the catalytic performance in oxygenates synthesis."

In general sum, they improved the synthesis of liquid fuels from Carbon Dioxide by fiddling with catalyst compositions.
Which is great; except that no one in Coal Country, with the exception of some scientists at Penn State University, seems to know anything about it.
As you will see in a report to follow, however, our US Government, as embodied in the Patent Office, did know all about it even before this article was published, as herein, by the American Chemical Society.
Far past time everyone, at least everyone in WV, PA and the rest of Coal Country read all about it, don't you think?
That is, of course, unless the West Texas oil field operators, who want to "sequester" CO2 in their fading petroleum reservoirs, all at the Coal industry's expense, have ordered everyone to dummy up.
