Many of the catalysts which are useful in Fischer-Tropsch synthesis are also capable of catalyzing the hydrogenation of CO2 to hydrocarbons. Our structure-function studies have shown that it is possible to control the selectivity of CO2 hydrogenation by specific iron-based catalysts to generate yields of C5 + hydrocarbons that are comparable to those produced with conventional CO based feedstocks."
Some things it might be thought-provoking to note: "Many ... catalysts ... are useful in Fischer-Tropsch synthesis", for instance, implies that scientists have identified many substances that will convert coal-derived synthesis gas into liquid hydrocarbons. And, we realize it's not obvious, but, by "conventional CO based feedstocks", we are compelled to presume they mean Carbon Monoxide generated by coal gasification in a low-oxygen atmosphere. Where else would they get CO? And, once again, through describing coal-based syngas, by inference, as a component of "conventional ... feedstocks", these Exxon researchers reveal that the knowledge of such conversion technologies is, in certain circles, common and routine.
