I don't know the specifics of this idea, but there's actually some merit to the more general idea you are denouncing. There are processes in which you can take some fuel, and add in some low-quality (i.e. low temperature) heat that would otherwise be wasted, and some CO2, and get more energy in the form of fuel out. Some of these things actually look like they have potential if you can get the catalyst.
