United States Patent: 4983296

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:

Texaco Prepares Coal for Gasification and Conversion | Research & Development.

United States Patent: 6447437

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";

United States Patent: 6903140

Herein, from that great greaser of sub-tropic American seas, and US coastlines and beaches, we submit an interesting refinement on the art of indirect Coal liquefaction; one that takes advantage of the fact that processes for the initial gasification of Coal most often co-generate a certain amount of Carbon Dioxide, along with the more-desired Carbon Monoxide and Hydrogen components of hydrocarbon synthesis gas.

Please note that our headline is not entirely accurate, since the technology we make report of is one which generates both alcohols and hydrocarbons from syngas which contains Carbon Dioxide.

United States Patent: 4104035

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.

United States Patent: 3971635

There should be nothing really, on a technical basis, conceptually new for you, presuming you to have followed our reports thus far, revealed by the Gulf Oil Corporation Coal gasification technology, confirmed as being viable by our own US Government, that we disclose herein.

Their intent is, simply, to generate as pure a mixture of Carbon Monoxide and Hydrogen synthesis gas, suitable for catalytic condensation, as via, for example, the Fischer-Tropsch process, into liquid hydrocarbon fuels, as possible.
