Methane conversion to higher hydrocarbons invention
 
Pursuant to our earlier report of United States Patent 1905520, issued in 1933 to German inventors, for the
"Conversion of methane into liquid hydrocarbons", we wanted to follow up by demonstrating that a domestic US knowledge base does exist for the conversion of Methane, as can be manufactured by the Sabatier recycling of Carbon Dioxide or the steam/hydro gasification of Coal, into liquid hydrocarbons.
 
Enclosed is a collection of three links with accompanying excerpts, with the first link above and all else following, which details something of what we think to be an integrated trail of technology development, though the entries aren't sequential, detailing that the methods have been developed which will enable the transformation of Coal-, or CO2-, derived Methane into Liquid Hydrocarbons via the intermediary of Acetylene.

In further support of the earlier documentation we've submitted, that Carbon Dioxide could actually be employed to improve the production of liquid hydrocarbons from processes of Coal conversion, we present, from China, additional evidence, not only of the fact that CO2 can be productively recycled, but that such recycling can be accomplished as part of an indirect Coal conversion process to generate greater amounts of useful products.

Abstract
A new process to integrate coal pyrolysis with CO2 reforming of methane over Ni/MgO catalyst was put forward for improving tar yield. And several Chinese coals were used to confirm the validity of the process. The experiments were performed in an atmospheric fixed-bed reactor containing upper catalyst layer and lower coal layer to investigate the effect of pyrolysis temperature, coal properties, Ni loading and reduction temperature of Ni/MgO catalysts on tar, water and char yields and CH4 conversion at fixed conditions of 400 ml/min CH4 flow rate, 1:1 CH4/CO2 ratio, 30 min holding time. The results indicated that higher tar yield can be obtained in the pyrolysis of all four coals investigated when coal pyrolysis was integrated with CO2 reforming of methane. For ... coal, the tar, water and char yield is 33.5, 25.8 and 69.5 wt.%, respectively and the CH4 conversion is 16.8%, at the pyrolysis temperature of 750 C over 10 wt.% Ni/MgO catalyst reduced at 850 C. The tar yield is 1.6 and 1.8 times as that in coal pyrolysis under H2 and N2, respectively."
---------
As we read this, and in other words, supplemental Carbon Dioxide can be added to Methane-rich gasses arising from Coal pyrolysis to nearly double, "1.6 and 1.8 times", the production of tars which can then be further refined into various commercial hydrocarbons.
