As in our recent post: 1940 CO2 + H2O + CH4 = Hydrocarbon Syngas | Research & Development | News; wherein is detailed: "US Patent 2,198,553 - Making a Synthesis Gas Mixture of Carbon Monoxide and Hydrogen; 1940; George Roberts; Assignee: The M.W. Kellogg Company, NY"; we have, as certified therein by the United States Patent office, known since the early days of WWII that we can "tri-reform" Carbon Dioxide, in a fashion very similar to that explained more lately by scientists, such as Chunsan Song and Craig Grimes, at Penn State University, and thereby generate a synthesis gas suitable for catalytic condensation into liquid hydrocarbon fuels.
Herein, we see that the above-named inventor of USP 2,198,553 continued his work, subsequent and relative to award of that patent, and, later in WWII, M.W. Kellogg, now a component of the Texas-based petroleum industry services company, Kellogg, Brown & Root, was assigned the rights to yet another patent, for equipment and physical plant related to the recycling of Carbon Dioxide through such reactions with Methane and Water vapor.
