[Gasification] Limonene fuel

[Thomas Reed]

Dear All:  

The active ingredient in the oils from orange, grapefruit, lemon, ... 
skins is "limonene".  (See http://en.wikipedia.org/wiki/Limonene). 
d-Limonene is a terpene (like turpentine) and is an excellent solvent, 
so is used in all kinds of magic cleaning solutions. 

It is high octane so could be used as an octane enhancer.  I have run my 
lawnmower on pure limonene. 

And it smells great...
------------------------------------------------------------------------
I wonder how much of the citrus crop limonene is now collected 
(expressed) and how much will be collected when oil hits $100/bbl.

Any info appreciated.
