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).

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.
