Our view is that the ethylene pathway is likely to be the most 
achievable of the gas upgrading options for smaller scale gasification 
(1-5 tonnes/hr feed rates). Produced as a co-product through a dedicated 
retort with depleted exhaust gases from this used to fuel a generator. 
Ethylene is relatively easy to form from CO & H2 as the catalytic retort 
needed operates at very modest temperatures and pressures (300oC & 
150psi). The ethylene produced can then be compressed and transported as 
for LPG. It could be added to existing reticulated natural gas lines, 
used directly as a transport fuel or as a feed stock for ethanol &/or 
plastics manufacture. The ultimate in recycling, generating virgin 
material from used. When we are over the current speed bumps on our 
journey we might have a crack at it (excuse the pun).
