We've many times documented the fact that Coal can be gasified, reacted, with Steam; and, be made thereby to form a "synthesis gas", or "syngas", that contains, predominantly, Hydrogen and Carbon Monoxide, in variable amounts and ratios; and, which ratios can be controlled to an appreciable extent, so that the resultant synthesis gas is suitable for catalytic, chemical condensation into specific types and ranges of both liquid and gaseous hydrocarbons.
One example of such technology that was developed early on, by a company that later became a part of Exxon, and then of ExxonMobil, can be seen in our report of:
