Rolf , Quite right C instead of F. I'm thinking of cherry red, on cast iron exhaust manifolds, as about the working temperature of fully loaded stationary engine on the correct fuel mixture. The system I have in mind would entail the reduction of nitrogen in the loop, if I can successfully produce oxygen enrichment with Zeolite adsorption. Nitrogen being replaced with CO 2 Does that sound feasible? Do you feel it might be possible to turn CO 2 into Methane with the addition of hydrogen?, there is certainly enough H2 and energy on hand to accomplish this. I seem to remember years ago. viewing on "Tomorrows World" a diesel engine running under 50 ft of water without any emission exhaust gasses,which were apparently re circulated, probably through Sodium Hydroxide.The point I am making is; all things are possible especially when heat and electricity are available.

GF, o, I have no info about passing "red hot exhaust" through the reaction zone. ut what do you mean by red hot ? 450-500 °C? hat's mighty hot enough to burn your fingers, but it would actually cool teh -zone down ! lso, if i understand you right, it would drag even more inert gas into the eaction , thus leading to a less rich gas. e want the energy, but not the stuff! nother thing would be an indirect heating of the dry biomass and introduce hese fumes into the running gasifier. But in the end this would not be more han a enlarged pyrolisis zone. We would still need some high temperature eat to crack the tars and reduce . nd yes, very dry biomass might ask for some additional water in form of team. on't know if I missed your point, if so, please explain!

This may sound like a stupid question, with CO 2 having the reputation of being an effective fire suppressant. Such is the reaction within the presence of steam,and the oxidization of cabon.CO2 will undergo a change, producing quality methane if the reaction is favorable. Such a reaction might not need very much additional air for pyrolises which should be sustained by the release of oxygen from the cracking process, thus reducing the nitrogen content of the gas produced. improving quality. I am thinking of simulating this reaction using "furnace coke" or charcoal, oxygen, nitrogen, steam, compressed air and scrap engine oil. inside a reaction chamber. I just need to get a handle on the quantities of these components to obtain the desired product. I have the metering system for the oil (fuel), and water (steam),and a few flow meters to control the gasses involved etc. The book mentioned in my last Email gave the quantity and BTU content of the gas obtained from various fuels including wood products.

Perhaps we should consider the ICE as the primary provider of heat for pyrolization, and build the gasifier around it." Yes , very much so! This is how Jim set up the GEK and it could even be mproved. ess energy to be provided by the oxidation process means less air/less itrogen in the process. It means a " richer poor gas" happy new year, btw Rolf _______________________________________________ he Gasification list has moved to [email protected] - please update your email contacts to reflect he change. lease visit http://info.bioenergylists.org for more news on the list move. hank you, asification Administrator _______________________________________________ The Gasification list has moved to [email protected] - please update your email contacts to reflect the change.
