message: Gasified coal is one source of syngas and so you could merge this topic into the syngas page, but to treat syngas fully, it is necessary to also mention that syngas can be produced by reformation of NG and by gasification of biomass.  NG production of syngas is infact quite important since several large auto and energy companies are now using or considering using this technology. —Preceding unsigned comment added by 213.223.50.144 (talk • contribs) 2 August, 2005 (UTC)

message: On March 27, 2006, User:Petri Krohn tagged this article with a suggestion of merging the Town Gas article into this article and the tag asks for discussion. I do wish that when someone tags an article like that, he/she would state the reasons for doing so here on the Discussion page to start the ball rolling. It would only be courteous to do so.
I oppose the suggestion most strongly. Anyone reading the Town gas article in detail will see that:
* It is badly in need of some good organization.
* A lot of it is very badly written. Some of it reads like some notes written on a piece of scrap paper. Other parts read as if they are just lists of what else is needed.
* It needs some thorough Wikifying.
In my opinion, before the Town gas article is merged with any other article, it needs a complete rework and rewrite by an expert in the field. - mbeychok 07:02, 28 July 2006 (UTC)
thread_title:  Regarding the suggested merging of the [[Town gas]] article into this one 

message: This article is essentially extremely good.  
I suggest that the article “Manufactured gas plant” should be merged here as it talks of the process and history while not the describing the plant.  This would also give the Manufactured gas plant article the global perspective that it currently lacks and would enhance this article with North American Information. http://en.wikipedia.org/wiki/Manufactured_gas_plant Jewell.box 20:12, 17 September 2006 (UTC)
thread_title:  Manufactured gas plant article globalisation and merge 

message: I have read the articles on "Town gas", "Wood gas", and "Water gas", and concur with those who suggest some revisions/merging are desirable. 
 
The three terms above are not in generally commmon use, and users searching WP might never find them directly.  They are all terms that should be replaced with one term:  Manufactured gas .  The chemistry of converting organic materials or carbon to CO and H2 are similar.  The three terms can be defined and compared in a new "Manufactured gas" article.  There may also be other WP articles that should be subsumed into the new "Manufactured gas" article. 
 
The "Manufactured gas" article should emphasize historical processes, the basic chemistry, the amount of energy required, and so forth.  Other terms such as "producer gas" should be introduced.  It's important to describe the way manufactured gas can be altered by the water gas shift reaction to produce a high-hydrogen manufactured gas.  This naturally leads to the modern era, where the historical "manufactured gas" technology has been replaced by quite sophisticated processes, using special catalysts, equipment, and sensors.  This is the SynGas industry, which makes feedstock for chemical plants, and so forth.  
The reason I suggest a comprehensive "Manufactured gas" article is that there has traditionally been a technological separation between which fossil raw materials are used as a feedstock to produce some kind of gas.  In early days, we used controlled oxidation of solid biomass, coal, or coke to manufacture gas, which was common before large quantities of natural gas had been discovered and made available.  Such "manufacturing" of gas has since dwindled or become obsolete (except for niche cases) because of the advent of natural gas.  Natural gas has now replaced almost all uses of "manufactured gas" for heating and electrical energy production.  
For special purposes, we now use controlled oxidation of natural gas to produce a mixture of gases, and this is called gas reforming.  Gas reforming is used extensively to produce industrially-important chemical feedstock material, or the reducing gas for iron ore reduction.  
    
Therefore, there is logic in creating an article on "Manufactured gas", with content and emphasis as described above.  The chemistry is still relevant, so it would be useful in other WP articles.  I suggest that the SynGas article cover modern industrial processes, such as natural gas reforming, hydrogen production, and processes for synthetic production of methane and other hydrocarbons (from any biomass or fossil substance), especially those operating commercially, plus any which are currently in serious development.  
If you try to include everything in the SynGas article, it will be really big, and a huge amount of work for one or more authors.  Thermbal 22:01, 16 November 2006 (UTC)

message: The scale and range of the information available on the conversion of hydrocarbon feedstocks into a 'syngas' which can then be used for synthesis of other hydrocarbon products is so large that putting it all under a single heading of "Syngas" would probably generate more confusion. This topic covers a number of industries (domestic gas manufacture, ammonia, hydrogen, methanol, Synfuels, GTL etc.) that have their own history, standards, terminology etc. I suggest that careful cross-referencing of these topics would make the topics more accessable to a reader.

replies: text: If these articles are to remain separate, not only should they be cross-referenced, but the individual articles should be strictly disambiguated from one another, that is, each article should address a narrow subject and refer to related articles when relevant.

message: Unicode character U+F044 is used in several equations. This Unicode code point is in the Private Use area, is not a standard encoding of whatever character was intended, and hence will not display properly with most fonts.
It appears that a capital Greek delta is intended and the expression is for the change in enthalpy. This is correctly represented as U+0394 "Greek Capital Letter Delta" in the Greek and Coptic Unicode block or U+2206 "Increment" in the Mathematical Operators Unicode block. (Note that Unicode also contains a variety of mathematical capital deltas in different styles.)
I have replaced these occurrences of U+F044 with U+2206 as the best Unicode representation of delta used to indicate change of a thermodynamic quantity (enthalpy in this case).Floozybackloves (talk) 15:33, 14 August 2010 (UTC)

message: Syngas, short for synthesis gas, is not producer gas.  The key difference is in nitrogen.  Producer gas is made with air in the reduction process, but there is no air in the making of synthesis gas. Synthesis gas is not made from producer gas and the machinery to make synthesis gas is not a downdraft gasifier, such as makes producer gas, by injecting air thru nozzles or tuyers, degrading woody biomass to a char... an exothermic process. 
Producer gas is a low energy gas, with perhaps 50% N, while synthesis gas is a high energy gas composed of significant quantity of H2 and CO.  Synthesis gas, derived from the water gas reaction is highly endothermic requiring significant energy input, which is more heat than being made in a downdraft gasifier. 
Producer gas is producer gas and synthesis gas is "syngas"... not one and the same.  Changes should include the producer gas and syngas new section.  — Preceding unsigned comment added by Woodgasmaker (talk • contribs) 02:38, 28 December 2010 (UTC)

Using carbon dioxide and hydrogen
CO2 can be split into CO and then combined with hydrogen (H) to form syngas. This method is being examined by the solar fuels-project of the Dutch Institute For Fundamental Energy ResearchDIFFER. The project envisions to produce CO from CO2, by treating this latter gas with microwave radiation. This appearantly was a popular method during the Cold war in Russian nuclear submarines as they needed to get rid of the CO2 gas without leaving a bubble trail.NWT magazine 6/2012.

thread_title:  BTU/area or BTU/volume? 

message: There's a claim that Russian nuclear subs used microwave devices to convert CO2 to syngas, so they wouldn't leave a bubble trail. Presumably this refers to carbon dioxide from the crew. It's quite well known that chemical scrubber devices performed this task on submarines and spacecraft, so I placed a 1983 US article from the open literature about their use on US subs. 
To confirm that the Russians didn't use a Tom Clancy method instead, I linked to the article about the Kursk sinking; the Oscar II was a cold war era nuclear sub, and it had scrubbers. UK subs most likely "got rid" of their excess carbon dioxide by using the gas to produce mixer for the officers' gin and tonic. Roches (talk) 17:15, 14 May 2015 (UTC)
