Dan, Ken, Gf and List,

Somewhere along the line, I think there is a misconception. The way I
understand plasmas is that in the direct line/area/volume of the plasma,
the temperature reaches 6000C and more. Now, that does not mean that all
of the gas has to be heated to that temperature, it is necessary only to
get some of the gas up to that that temperature so that after
recombining, the cracking reactions will take place. 

Also, if I recall correctly, ionization of droplets ala mist
precipitators causes the droplets to absorb electrical charge sufficient
for them to deviate in a downstream magnetic field. If the initial
ionization energy is stepped up, sufficient energy could be absorbed by
the tar droplets (I am assuming preferentially to the gas) for them to
heat up beyond the cracking temperature. This will break them down. 

Am I missing something here?

4.7 GHZ microwave has an affinity for water,metals, carbon etc.
Gases which contain these materials will be subjected to the electrical excitation 
caused by this frequency, readily being plasmarized within a suitable cavity.
The electronic bonds attaching molecules are neutralized within this plasma.
the reconnection occurs on cooling. If oxygen is deficient within the cooling process
The reaction will produce gases such as CO and H2, from water and CO2.

The reaction, which occurs within a retained area, the wall of which has to be thermally protected or it will melt.
The plasma will occupy all of the space containing the gas being processed.
In the latest developement of electrode less vapor plasmas, a nitrogen shielding gas is admitted within,and 
around the edges of the container for cooling purposes.
It is hoped that surrounding this chamber with unburned bio fuel will provide sufficient cooling
in conjunction with saturated steam.
