Herein, via a report of research from Ireland, we confirm and support our earlier reports of developments, accomplished by Penn State University, and others, whereby Carbon Dioxide can be reacted with Methane, which can itself be synthesized, by Sabatier technology, from Carbon Dioxide; or, by hydro-, or steam-, gasification technology, from Coal; to synthesize higher hydrocarbons of utility and value.

"Carbon Dioxide Reforming of Methane over Molybdenum Catalysts
D. Treacy and J.R.H. Ross; Centre for Environmental Research, University of Limerick, Ireland
Introduction: CO2 reforming of CH4 is a subject of considerable interest due to the ability of the reaction to produce synthesis gas with low H2/CO ratios; higher ratios can be obtained by combining the process
with steam reforming or partial oxidation. Ni-based catalysts are commonly used for reforming reactions but suffer from problems due to carbon deposition. Noble metal catalysts, in particular Pt-ZrO2, have been shown to have high activities for CO2 reforming while resisting significant C deposition; however, because of their relatively high cost, their potential for use as CO2 reforming catalysts is limited. The group VI transition metal carbides, WC and Mo2C, have been reported to have catalytic properties similar to those of the
noble metals and ... unsupported Mo2C and WC have good activities as CO2 reforming catalysts. However, these catalysts deactivated after short periods of use at ambient pressures. We have shown that the deactivation of the carbides is caused by the formation of the corresponding oxides. In this paper, we show that when Mo2C is supported on a variety of supports, the resultant catalysts are somewhat more stable.
Results and Discussion: ... The Mo2C-Al2O3 sample gave the highest initial activity, with a CO2 conversion of 63%, while Mo2C-ZrO2 also gave a relatively high CO2 conversion of 48%. ... the Bi-Mo2C-ZrO2 catalyst gave a CO2 conversion of 74.6% ... .
Conclusions: Of all the catalysts tested Mo2C-ZrO2 was the most promising due to its stability and reasonably high activity. The activity of this catalyst can be improved by increasing the reducibility of the
precarbided MoO3 surface material. This could be achieved using a number of methods, including low calcination temperatures and the addition of small amounts of a Bismuth promoter to the catalyst.

We won't attempt too much discussion of this report, except to note what should by now be obvious from all the other, similar, reports we have already brought to your attention:
The technology exists to reclaim Carbon Dioxide, and to utilize it in bi-reforming and tri-reforming reactions with Methane, which can itself be synthesized from Carbon Dioxide, to manufacture "synthesis gas", which, as all our readers should by now know, can be further catalyzed into direct replacements for the liquid fuels we currently use.
Why aren't we doing that, instead of allowing Cap&Trade taxation schemes and Oil Field Sequestration scams to be shoved down all our Coal Country throats?
