Syngas
editThere is confusion as to the nature of syngas. The mixture usually known as synthesis gas is produced in the water gas shift reaction
- CO + H
2O → CO
2 + H
2
In the article it appears that the reverse reaction is carried out, producing carbon monoxide. Please clarify.
The novelty of this process is the production of carbon monoxide from carbon dioxide. The next step, Fischer-Tropsch synthesis is already used commercially; see Sasol, for example. Petergans (talk) 09:27, 6 May 2015 (UTC)
- Syngas is a gas mixture of two main components, carbon monoxide and hydrogen. There can also be carbon dioxide in the mixture, but it is lower than 20% or so. See some examples of the composition of syngas generated from coal gasification process. There are many ways to create syngas. Syngas generated from coal that I mentioned is one of them. The water gas shift that you mentioned is the second to last step of the syngas generation from natural gas. That step is to boost up the hydrogen in the mixture at the cost of lowering carbon monoxide and increasing carbon dioxide. The last step is actually to try to absorb carbon dioxide out of the mixture. Another syngas generation method is mentioned in the article. It is from a reverse water-gas shift process to generate syngas from carbon dioxide and water. Z22 (talk) 03:06, 7 May 2015 (UTC)
- Carbon monoxide + Hydrogen are the inputs for the F-T Reactor.
- Syngas via Steam reforming is produced where methane is contacted with steam over a heated catalyst at high pressures and temperatures to produce syngas.
- CH4 + H2O ⇌ CO + 3H2

Not magic
editThis process is not magic; the law of conservation of energy still applies. The inevitable hype in the media has already begun, with at least one headline claiming that fuel is being created "using just carbon dioxide and water." If only it was that simple. The fact is that the process consumes carbon dioxide, water, and electricity. Since e-diesel has a high energy density, we can safely assume that the energy requirements of the process are very substantial. The word "electricity" has thus just been added to the third sentence of the lede in an attempt to keep the reader in some sort of sober contact with the realities of the laws of physics.
