Breakthrough in CO2 to Fuel Conversion. Now, researchers at MIT and Harvard University have developed an efficient process that can convert carbon dioxide into formate, a liquid or solid material that can be used like hydrogen or methanol to power a fuel cell and generate electricity. Potassium or sodium formate, already produced at industrial scales and commonly used as a deicer for roads ...

Liquefaction is the process of converting solid coal into liquid fuels. The main difference between naturally occurring petroleum fuels and coal is the deficiency of hydrogen in the latter: coal contains only about half the amount found in petroleum. Therefore, conversion of coal into liquid fuels involves the addition of hydrogen.

Direct liquefaction is a possible way of converting solid biomass material into liquid fuel under increased pressure in the presence of hydrogen and a catalyst. Dry biomass is described by the chemical formula CH O, liquid fuels by CH 2 and hence the chemical basis of direct liquefaction can be described by the reaction [17] (1) CH ...
