[Gasification] coal coocking

[astrupgaard]

Tom
Maybe you should look at the IBUS or the Maxifuels projects. Former ELSAM
and Energy E2 - now both under DONG Energy head the demonstration activities
together with DTU, Novozymes and other internationally known partners.
http://www.bioethanol.info/IAM/ibus_IAM.html or
http://www.biofuels.dk/Maxifuels.htm


They cook the straw or MSW or…? - continuously - expand/open it during
pressure release. They ferment and make bioethanol, fertilizer and charcoal
without all the alkali, chlorine etc. - very suitable as fuel in the
powerboiler or for that sake in other boilers or stoves.

Is this going to lead us back to Changing World Technologies Thermal
conversion Process of "thermal depolymerization"?
http://www.changingworldtech.com/what/index.asp Chicken feathers!

See http://www1.eere.energy.gov/biomass/pyrolysis.html

ECN (Netherlands) has evaluated biomass hydrogasification for SNG
production. "They evaluated the SNG production by means of
hydrogasification. In the hydrogasification process, hydrogen is fed
together with biomass to an autothermal gasifier at 30 bars. The hydrogen is
to be supplied by industrial rest streams. The
energy input of the incoming hydrogen is about the same as the thermal input
of the biomass.
For a 50 MW plant a production price of 22 €ct/ Nm3 was calculated."

Ian Bywater used a hydrolysis method that seemed to have the same basic
method for his convertech New Zealand firm, now not trading though Ian is
still active. He claimed his process was  autothermal or autolysis which I
took to mean it required no additional chemicals or heat input. His process
yielded oils though.
