This how we try to model tom make simple simple process where
indirect heated pyrolysis is made simultanely along with gasification
pyrolysis oil leading to Gas methane, C02 , CO which has to be shifted
using steam whch can increase the co2 along with H2. This reformed gas
obtained as co product of activated charcoal, methanol , unconverted
syngas for small CHP.
We also think of solid charcoal and methane , high temperature
pyrolysis alterative to H2:CO content to make less CO2 syngas
, suitable for small scale Biomass 2 liquid project such as GEK low cost
technology, to make multy products

ore con
This can be called as reformed gas /
The use of reforming , reformed gas can be the correct instead of
syngas
The use of pyrogas is very clear with repect to the product and process,
the same to for producer gas , when you come to syngas ,it can be defined by
the process , but only the product, making it use not specific
