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

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.

For comparison, a diesel generator of this size (20kWe) has a rate of about 1,1 kgeqCO2/kWh.

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.
