It is a little known fact that CO2 can be converted into Methane. Years <br>
ago this was expensive and quite a difficult reaction to perform, <br>
involving very high pressure and temperature reaction chambers together <br>
with exotic catalysts. However,over the years since "Sabatier" <br>
discovered how to perform this remarkable feat, fuel and chemical <br>
refiners have developed a lower cost approach. But fairly high <br>
temperatures are still required, making the process expensive. <br>
Fortunately, there is considerable waste heat available at the exhaust <br>
manifold of your Engine to supplant some of this cost. Additional heat <br>
is also required in order to re-arrange the molecules back into fuel, <br>
this is where a stream of hydrogen from an out side source such as your <br>
gasifier will help, as will super heated distilled water. The <br>
additional heat can be provided by a plasma produced by an arc or an <br>
electrode less plasma produced by Electromagnetic means. nothing more <br>
than 2kw. <br>

Hello to all,<br>
<br>
<br>
<br>
Does anybody have an idea of the CO2 emission after generator?<br>
<br>
For comparison, a diesel generator of this size (20kWe) has a rate of <br>
about 1,1 kgeqCO2/kWh.<br>
<br>
<br>
<br>
Thanks <br>

Jeremy and all<br>
<br>
<br>
<br>
Both gasoline and diesel are approximately -CH2- chained together. <br>
Their combustion can be written<br>
<br>
<br>
<br>
CH2 + 3/2(O2 + 3.76 N2) ==> CO2 + H2O + 5.64 N2<br>
<br>
M 14. 44. 18 158. 220<br>
<br>
<br>
<br>
So the all important Air/Fuel, A/F ratio is 220 /14= 15.7<br>
<br>
<br>
<br>
The ratio is often given as 14.7. Maybe this is due to the presence of <br>
unsaturated and aromatics with lower H/C ratios.<br>
<br>
<br>
<br>
The oxygen sensor is capable of measuring very small amounts of <br>
unburned fuel or oxygen in the exhaust and adjusting the A/F ratio for <br>
perfect combustion. <br>
<br>
<br>
<br>
Diesel combustion is always lean.<br>
<br>
<br>
<br>
Lucky us that our cars are so clean.<br>
