[Gasification] "Continuous analysis of elemental emissions fromabiofuel gasifier"

[Tom Miles]

Jeff, Doug,

We dreamed about making this split with pyrolysis and with gasification. In
both cases some stays with the char but most of the water soluble inorganic
elements, like sodium, potassium, chlorine and sulfur go with the vapors or
gas.

Hi Jeff,

You raise an interesting point:

Cannot comment on Ag waste, but it seems that there is validity for some 
elements to leave  the biomass as pyrolysis gas, leaving the carbon to then 
combust or gasify without problems. I refer to mainly woody biomass, but 
doubt if the same could be achieved with Ag waste , which can have a high 
silica content.

It is all theory until you try it with your choice of waste, so have a try, 
it beats reading about it (:-)
