The treated coal is loaded into a bulk pile.

Process of producing a treated coal, by heating the coal to remove volatiles and drying the product to produce a treated coal consisting essentially of carbon and hydrogen.

Coal is contacted, or treated, with at least one aromatic alcohol and/or cycloaliphatic alcohol to solubilize at least a portion of the treated coal.

The treated coal is optionally bioconverted to produce one or more hydrocarbons, such as methane.

Coal is mainly carbon; the general principle is that coal treated with hydrogen gas at high pressure and temperature (“hydrogenation”) resulted in oil.

During the same period, Abraham Darby developed the production of cokeCoke is a coal derivative obtained through pyrolysis.

In nearly three years of burning the treated coal, the Duke power plants collected several million dollars in federal subsidies.

The contact pH of the treated carbon remains within the potable pH range for treatment of more than 100 bed volumes.

Coal gas plants produced gas and many by-products, including cokeCoke is a coal derivative obtained through pyrolysis.
