is that the ethylene pathway is likely to be the most <BR>achievable of the
gas upgrading options for smaller scale gasification <BR>(1-5 tonnes/hr feed
rates). Produced as a co-product through a dedicated <BR>retort with depleted
exhaust gases from this used to fuel a generator. <BR>Ethylene is relatively
easy to form from CO & H2 as the catalytic retort <BR>needed operates at
very modest temperatures and pressures (300oC & <BR>150psi). The ethylene
produced can then be compressed and transported as <BR>for LPG. It could be
added to existing reticulated natural gas lines, <BR>used directly as a
transport fuel or as a feed stock for ethanol &/or <BR>plastics
manufacture. The ultimate in recycling, generating virgin <BR>material from
used. When we are over the current speed bumps on our <BR>journey we might
have a crack at it (excuse the pun).<BR><BR>Peter<BR></FONT></BLOCKQUOTE></DIV>
<DIV>DD I like this approach. Ethylene has the fossil fuel world buzzing here in
Ohio because they found a lot of natural gas liquids in the overlap zone of the
Utica Shale. ( The overlap zone between the oil rich shale to the west and the
gas rich shale to the east.) Butane and Propane, often found with the Ethylene
is also in real demand as a chemical feedstock and might be produced in similar
fashion. Other places around the world were not blessed with such natural
resources and might really benefit from creating their own. </DIV>
