Dear Booster Reed,
How much ton of biomass will burn to produce 1 ton of CO2?

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

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

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