We have, in multiple submissions, documented the "Tri-reforming" technology espoused by Chunsan Song, and others, at Penn State University, wherein Carbon Dioxide is reacted, recycled, with Methane to synthesize higher hydrocarbons suitable for refining into liquid fuels.
We have also documented that, not only can the Methane needed for reforming CO2 be manufactured via the steam-, or hydro-, gasification of Coal, it can also, as in the Sabatier process, be itself synthesized from Carbon Dioxide.
