Production of gases from carbonaceous solids
More than one half of a century ago, the United States Petroleum Industry and, by extension, through approval and issuance of the United States Patent we enclose in this dispatch, our United States Government, knew full well, that: not only could Coal be converted, through gasification and subsequent catalytic condensation, into liquid hydrocarbon fuels, but, through inclusion in the gasification process, so could Carbon-recycling botanical products and, even, Carbon Dioxide itself.
Such a concept shouldn't be unfamiliar to you, assuming you to have followed our posts thus far.

More than a year ago, we alerted you that the German engineering giant, Siemens AG, had, through a United States scientist in their employ, developed a technology for the practical and profitable recycling of Carbon Dioxide in the synthesis of hydrocarbon fuels; and, had applied for a US Patent on that technology.

Over the past several years, we've many times referenced and documented the development of an extraordinary body of Carbon conversion technology by New York's former Texaco, Incorporated, before they, and their familiar and famous red star, in 2001, got homogenized into the more ambiguous, regimental red and blue blazes of Chevron.
Our most recent report concerning Texaco and their Carbon conversion expertise is accessible via:

Although the focus of our reportage, concerning the profitable use of the gaseous byproducts of Coal combustion, has centered primarily on their use in the synthesis of hydrocarbon fuels, as seen in:
USDOE Algae Recycle CO2 into Liquid Fuels | Research & Development; concerning: "Liquid Fuels from Microalgae; 1987; National Renewable Energy Laboratory (NREL), Golden, CO; USDOE; Abstract: The goal of the DOE/SERI Aquatic Species Program is to develop the technology to produce gasoline and diesel fuels from microalgae";

In many of our reports documenting and explaining how Coal can, through an initial gasification, be indirectly converted into liquid hydrocarbon substitutes for natural petroleum-based fuels, it can be seen that technologies wherein Coal is first "slurried" in one liquid or another, prior to gasification and conversion into the Carbon Monoxide and Hydrogen components of hydrocarbon synthesis gas, are often specified.
A representative phrase describing that procedure might be: "comminuted coal is first slurried in a mixture of", wherein "comminuted" means ground into fine particles, with the sizes of the particles often specified; and, wherein "slurried" simply means that the "comminuted coal" is mixed thoroughly into the liquid to form a thick suspension which can be pumped, and forced through nozzles into a combustion zone.
