<p class=MsoNormal>Anna, <o:p></o:p></p>
<div>
<p class=MsoNormal>Thanks for your enquiry but we have not tested Jatropa per
se. I am confident though, that somewhere in one of the above copied
list serves/newsgroups, there is the answer to your questions about Jatropa
combustion and emissions..<o:p></o:p></p>
<div>
<p class=MsoNormal><o:p> </o:p></p>
</div>
<div>
<p class=MsoNormal>As far as its use in briquette making –of the wet process
ambient temp low pressure type which we extoll–, it is both tempting resource
and likely to be a very problematic one... While the cake can serve
as a fuel in its own right, if it is symbolic of the other types of seed cakes
expellate we have attempted to use, it can cause problems when added into
the mix of wet pulped agro residues, and compressed / dewatered, into a
briquette, in the usual fashion.<o:p></o:p></p>
</div>
<div>
<p class=MsoNormal><o:p> </o:p></p>
</div>
<div>
<p class=MsoNormal> The reason is that the the residual adhered oil in
said cake tends to lubricate the otherwise tightly compacted,
elastically deformed, and randomly aligned, interlocking fibers
--which do the real work of binding of the briquette. The resulting briquettes
are mushy and weak even after weeks of drying in the open (sunny) air. The same
blends-- without such seedcake additives-- typically dry to ambient humidity in
a few days under the same climatic conditions. <o:p></o:p></p>
</div>
<div>
<p class=MsoNormal>Of course lowering the proportion of the expellate will have
better results...I unfortunatley do not have any numbers on this though. <o:p></o:p></p>
</div>
<div>
<p class=MsoNormal><o:p> </o:p></p>
</div>
<div>
<p class=MsoNormal>What I know you <u>can do,</u> is use the "foots"
of the oils -the "oily chunky mix of saturated bits of the plant which
managed to get through the seive and settle out of the oil. This stuff is
otherwise useless. It always accumilates on the bottom of the oil collection
tray and the floor of such pressing operations. It is useful to briquetters
however when they dip their already-dried briquettes in it <to a
depth of about 1/4th their height for a few seconds. That will consumme
about 1-3 cubic cm of the material. Provided that the other ingredients
and prep process has been done correctly, a very nice quick-igniting --yet
still structurally integral-- briquette is the result.<o:p></o:p></p>
