We have known, in the United States of America, for a very long time that Coal can be combined with Carbon-recycling, renewable wastes, or deliberately-cultivated botanical materials, and then "gasified" through a process of partial oxidation, i.e., partial combustion, with the products of such gasification including, typically, a blend of Carbon Monoxide and Hydrogen - - called "synthesis gas", or "syngas", which can be catalytically condensed via one of several long-known processes into liquid and/or gaseous hydrocarbons - - and, in some cases, depending upon what, if any, gasification catalyst is utilized, a lesser or greater volume of Methane.
