Carbon dioxide reforming (also known as dry reforming) is a method of producing synthesis gas (mixtures of hydrogen and carbon monoxide) from the reaction of carbon dioxide with hydrocarbons such as methane with the aid of metal catalysts (typically Ni or Ni alloys).
Methanation is the conversion of carbon monoxide and carbon dioxide (CO x) to methane (CH 4) through hydrogenation. The methanation reactions of CO x were first discovered by Sabatier and Senderens in 1902. [1] CO x methanation has many practical applications.
The CO, a byproduct of the reaction, may be collected and used as a low-grade fuel [21] or reacted with water to form methane (CH 4 ) for use as a primary fuel. [ 22 ] [ 23 ] As an alternative use, an oxygen generation system could fill a small oxygen tank as fuel-oxidiser to support a sample return mission . [ 24 ]
A major drawback of using coal as a fuel source is the emission of carbon dioxide and pollutants, including sulfur dioxide, nitrogen oxide, mercury, and particulates. Almost all coal-fired power plants use pulverized coal combustion, which grinds the coal to increase the surface area, burns it to make steam, and runs the steam through a turbine ...
A catalytic heater is a flameless heater which relies on catalyzed chemical reactions to break down molecules and produce calefaction (heat). [1] When the catalyst, fuel (e.g., natural gas), and oxygen combine together, they react at a low enough temperature that a flame is not produced.

Formic acid can be used directly in formic acid fuel cells or indirectly in hydrogen fuel cells. [39] [40] Electrolytic conversion of electrical energy to chemical fuel has been proposed as a large-scale source of formate by various groups. [41] The formate could be used as feed to modified E. coli bacteria for producing biomass.
