We have many times made reference to, and reported on, ExxonMobil's "MTG"(r), methanol-to-gasoline, technology, wherein the Methanol is posited to be made from Coal.
The latest, what we take to be key, piece of that Coal conversion technology was, we think, encapsulated in a United States Patent we earlier made report of, as in:
Mobil Oil Coal to Methanol to Gasoline | Research & Development; which concerned:
"United States Patent 4,447,310 - Production of Distillates through Methanol to Gasoline; 1984; Assignee: Mobil Oil Corporation; Abstract: A process for producing a wide slate of fuel products from coal is provided by integrating a methanol-to-gasoline conversion process with coal liquefaction and coal gasification."

We have earlier reported on the development, by the same team of USDOE Idaho National Laboratory scientists we cite herein, of the technology sometimes labeled as "Syntrolysis", wherein a blend of Carbon Dioxide and Water, or Steam, is electrolyzed, and/or thermo-chemically decomposed, and made thereby to form a resultant blend of Carbon Monoxide and Hydrogen, a synthesis gas, which can then be catalytically reacted; and, be thereby chemically condensed into liquid hydrocarbons.
Examples include:
USDOE Idaho Lab Recycles More CO2 | Research & Development; which discloses: "Model of High Temperature H2O/CO2 Co-electrolysis"; and:

The Dutch scientists who worked for Houston's Shell Oil Company were, in their formal Summary of the United States Patent we enclose herein, quite succinct about what their invention was, and is, all about.
It is, as they state: "a process for preparing liquid hydrocarbons from coal".
But, it is "a process for preparing liquid hydrocarbons from coal" with a slight twist; and, perhaps, with some unstated, though valuable, potentials.
Note, that, in the course of their Disclosure, these Shell scientists reveal that their Coal-to-Gasoline process generates one significant by-product: Isobutane.

United States Patent Application: 0100083575
Buried deep in the "Background" section of the United States Patent Application we enclose herein, for a process developed by that lovable oily giant, ExxonMobil, is a statement which reveals the true intent and purpose of the invention, as follows:
"One established route to the production of hydrocarbon liquids is the gasification of carbonaceous materials followed by the conversion of the produced synthesis gas to form liquids by processes such as Fischer-Tropsch and its variants.

Via: Ethane from Coal at 8 Cents a Pound | Research & Development; wherein it's disclosed, in the report: "Synthesis of Light Hydrocarbon Gases from Coal Gas; S. Singh, et. al.; Battelle Columbus Labs, OH; National meeting of the American Chemical Society;1976"; we can learn that, in 1976, a process had been developed which would, in addition to, primarily, synthesizing Methane from Coal, also generate, as a by-product, significant quantities of Ethane, at a cost, then, of only 8 cents a pound.
Again, the primary product of that technology is Methane, and, by now, from our many reports concerning the fact, including:Standard Oil 1944 CO2 + CH4 + H20 = Aviation Fuel | Research & Development | News; you should know, that, once we have Methane, CH4, as produced by, for just one example, the Battelle Labs' process, from Coal, we can react such Coal-derived Methane with Carbon Dioxide, recovered from whatever handy source, and thereby synthesize some very useful, and valuable, hydrocarbon compounds.
