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).
