US Patent for Conversion

Here is yet another United States Patent, issued more than twenty years ago, verifying that, in the expert opinion of our own United States Patent Office examiners, coal can, in a practical way, be converted to useful gasses, liquids and solids.

"Apparatus for the conversion of coal to gas, liquid and solid products
Abstract
An apparatus is provided for converting coal to gas, liquid and solid products. The coal is subjected to a pyrolysis reaction at a temperature of at least about 260.degree. C. in the presence of a hydrogen-containing gas, and the resultant solid residue subjected to a gasification reaction with oxygen and steam at a temperature of at least about 482.degree. C. thereby generating the necessary hydrogen-containing gas for the pyrolysis reaction and producing a solid product. Heat generated in the exothermic gasification reaction is transferred to the pyrolysis reaction, so the apparatus does not require any external source of heat except for means to control the temperature of the gases passing to the pyrolysis reaction chamber. The gaseous fraction generated in the pyrolysis reaction is cooled to produce liquid and gas products, preferably after having first been subjected to a Fischer-Tropsch reaction.

This process, is one of many, some not, seemingly, patented but held instead as proprietary information by major corporations such as Sasol, ExxonMobil and Phillips, as we've documented. Note, however, that, at the end of the Abstract, we return to the "Fischer-Tropsch reaction".
The technologies, there are many, apparently, to convert our vast reserves of coal into much-needed liquid fuels and chemicals exist, as verified by our own US Patent Office. Why aren't we yet employing any of them, in a practical and organized way, to free ourselves from foreign economic bondage, to help ensure our domestic security, and to keep our own citizens fully employed?
