It's a gas when it comes out of the catalytic converter module.....then it's condensed. I believe mention was made at the AGM to actually add a separation module........then you'd have Diesel AND Gasoline coming out........z
That exact method was stated by John at the demo after the AGM. The output he was getting was termed "near diesel" because it still had a percentage of output in the "gasoline" range mixed in. According to John, by adding another condensor they could separate that during the process and end up with diesel, gasoline, and gases to be used to run the process.
Adding a distillation step to the P2O machine shouldn't be a big problem.
It's called a differential condensor... the reactor is already evaporating all of the non-tar components at 300*C. It's just a matter of a properly configured cooling column.
