Re: GAS-L: gasification of rice husk (shell)

 The pyrolysis results obtained are on expected lines. But to get complete
idea you should also provide the proximate analysis of coconut husk (Not
Rice husk as mentioned in subject). I think the moisture of 7.1% is high
because char may have been exposed to the atmosphere. With yield of 30%
there should hardly be any moisture content in the char.

 The results also show that the pyrolysis was only partial which depends
upon temperature or rather temp. profile, time of pyrolysis and size of the
substrate.

 Feel free to ask any questions.
