Hi Angie,<br>
<br>
From my notes you will have around 50 tonnes of shell. Probably the
quickest and easiest would be to build a deep cone Kon Tiki kiln
<a class="moz-txt-link-freetext" href="http://www.ithaka-institut.org/en/ct/101">http://www.ithaka-institut.org/en/ct/101</a> where there is a link to a
presentation on the technology.<br>
<br>
Below is an image of coconut char produced from one of our small
round hearth downdraft gasifiers optimised for both char and clean
gas. This is a from a pilot unit in the Pacific Islands undergoing
trials. The image is taken from the front with the char bin door
removed, the top (narrowest point) of the char column is the entry
below the gasifier.<br>
<br>
The unit gives around a 15% recovery on a dry basis, fixed carbon is
>85%. The coconut shell is crushed to average piece sizes of 30mm
before feeding to the gasifier.<br>
<br>
All the best with your project.<br>
<br>
Peter<br>

<div>Hello all - Cheers from Bali!</div>
<div>I am part of a team developing various coconut products
ranging from virgin coconut oil, palm sugar, coconut flour,
etc.etc.</div>
<div>We will be processing around 1 million coconuts this year
and want to effectively, efficiently, and affordably utilize
the coconut shell as a value add product.</div>
<div>Anyone have experience with making coconut charcoal? Or a
step further, making activated carbon with coconut shells?</div>
<div>In the future (year 2) we will be incorporating biomass
gasification using coconut shells, but for the upcoming year
we are looking for solutions to our coconut shell surplus.</div>
<div>Thanks in advance,</div>
<div>-Angie <br>
