First, as indicated by a number of web-based resources, the named inventor, one Paul Ahner, in this United States Patent Application, which discloses a technique wherein Carbon Dioxide can be utilized in a process of Coal gasification, and be converted therein, along with Coal, into a synthesis gas suitable for catalytic condensation into liquid hydrocarbons, was once a resident of Pittsburgh, PA; where he worked, in the employ of the former Gulf Oil Corporation, as a scientist focused on Coal and Carbon conversion technology.
We are, in fact, including, as a postscript, further documentation of Ahner's Coal conversion and Gulf Oil background.
Now living in Oklahoma, Ahner seems to be working as an independent consultant to the petroleum industry.
