To produce hydrogen from coal, the process begins with partial oxidation, which means some air is added to the coal, which generates carbon dioxide gas through traditional combustion.
To reverse this trend, a new process for producing carbon products is needed. The process must be economically competitive with current processes, and yet be environmentally friendly as well. The solvent extraction process developed uses mild hydrogenation of low cost oils to create powerful solvents that can dissolve the organic portion of coal.

Test Series. Coal is a fossil fuel formed from the remains of plants that lived and died millions of years ago. It has been an energy source for centuries and has various associated products. Coal Products generate heat, industrial power generators, make cast iron, and more. Coke, tar, and coal gas are all byproducts of coal processing.
steam to produce a higher hydrogen content gas stream. Gasification Gasification is a process in which coal or biomass is converted into gaseous components by applying heat under pressure and in the presence of air/ Hydrogen can be produced using a variety of resources including biomass, hydro, wind, solar, geothermal, nuclear, coal with carbon ...
Coal Combustion Residuals (CCR) are produced in the creation of electricity in coalfired power plants and are the remnants from the burnt coal (, ash) that are collected from the flue gases and boilers, as well as other byproducts produced as part of air quality emission control systems. The primary CCR materials include:
Coal liquefaction is a process of converting coal into liquid hydrocarbons: liquid fuels and process is often known as "Coal to X" or "Carbon to X", where X can be many different hydrocarbonbased products. However, the most common process chain is "Coal to Liquid Fuels" (CTL).

Amounts of Byproducts Produced Large quantities of coal are used annually to produce electricity. For example, coal consumption for this purpose in Georgia alone averages about million Mg annually and results in million Mg of fly ash and million Mg of bottom ash (McIntosh et al. 1992). Therefore, the weight of fly and bottom ashes
While integrated players produce steel from iron ore and need coal as a reductant, EAF producers use steel scrap or direct reduced iron (DRI) as their main raw material.
