We had earlier informed you that Exxon-Mobil, in their "MTG" (r) process, were converting Methanol, manufactured from coal, into Gasoline through the mediation of their "ZSM" zeolite catalyst. They are commercializing that technology, as we've documented, in China and, perhaps, New Zealand.
We have also documented for you that zeolites can be found, and "mined", in abundance, from coal ash accumulations.
We submit the enclosed in further support of that knowledge. Please understand, as we have earlier explained, that "hydrotreatment", as used herein, is somewhat synonymous with "hydrogenation". Hydrogen is being added to high-carbon coal products to effect their transmutation into liquid hydrocarbons. West Virginia University, in their "West Virginia Process" for coal conversion, as we understand it, uses the Hydrogen-donor solvent, Tetralin, to liquefy and "hydrogenate" coal into such synthetic "petroleum".
There are, though, as we've tediously repeated, numerous ways in which to skin the coal conversion cat, and thus make the United States self-sufficient in liquid fuels. Herein, as excerpted below, is even more information on how yet another coal use waste can be employed to help make that happen:

Abstract
Catalytic activities of high-silica zeolites of ZSM type and also bi-zeolite catalysts HY-ZSM and LaY-ZSM in the hydrotreatment of a wide fraction of liquefaction products from brown coal (328–698 K boiling range) were determined. All the zeolites were modified by Mo and also Pd, Co and Ni loading. It was shown that ZSM use provides an opportunity to hydrogenate nitrogen compounds selectively in the presence of sulfur compounds. Removal of phenols does not restrict the general hydrotreatment process. A considerable increase in activity was found on changing from ZSM to the bi-zeolite systems HY-ZSM and LaY-ZSM."
And, we must affirm yet again that Carbon Dioxide, as well, can be "hydrotreated", hydrogenated, as we have thoroughly documented, into additional hydrocarbon, fuel, liquids.
