The US burns hundreds of tonnes of wood waste a day: in steam it could turn it into petrol and diesel. For 5% of the cost of Fossil Fuels.
Carbohydrates are Cm(H2O)n
Wood is approximately 50% carbon, 42% oxygen, 6% hydrogen, 1% nitrogen, and 1% other elements (mainly calcium, potassium, sodium, magnesium, iron, and manganese) by weight. So we use a semi-permeable membrane to separate the CO2 – the other gasses we pass through fire tubes in a boiler.
So as we burn wood waste, we get CO2 residual air, and ash. We get 593oCelsius. We can take off 30% of the gas, and get loads of steam at 120oC, 4 atmospheres.
So when we mix the steam with the hot CO2, we still get a gas temperature of 420oC. We extract the ashes from the large reactor vessel. And sell it as concrete aggregate.
So the steam and hot CO2 do the Sabatier reaction – above 370oC, and 1 atmosphere. So vent the steam to 1 atmosphere.
1 CO2+3H2O+E->CH4 +He+O3
We use semi-permeable membranes, to separate the He and O3 gases: both of which have high value, and are worth cooling and selling.
Today natural gas, CH4, has high value – and can be sold direct. As a fuel gas.
The rest of the CH4, we pass down through 4 titanium honeycomb catalyst, and heptane fuel oil drips out – plus methane we need to recirculate.
We repeat the trick, and get C12H26 etc.,. The average chemical formula for common diesel fuel is C12H23, ranging approximately from C10H20 to C15H28.
So we collect the fuel oil, and burn some of it, so we can pass hydrocarbon gas through a refinery, and get out biochemistry petrol and diesel. The trees take in the CO2 to grow – that is now in the fuel oil.
So as we burn it, there is no net increase of CO2 in the air – that is biologically impossible even with Fossil Fuels. But here we release the CO2 trees took in to grow over the last year. No net increase of CO2 in the environment.
Historically, CO2 only doubles in a natural ice-age. It is fixed at 2 parts per million today – though it is at 4ppm OVER THE ARCTICS.
So we turn wood waste into massively cheap and plentiful petrol and diesel. The price is linked to supply, so petrol prices are going to crash to below $10 a barrel. Within 5 months.
Nobody will buy the over priced crude from Saudi Arabia and Russia.
