[Terrapreta] Overview on biochar production methods

[Tom Miles]

Robert,

 

Your mention of Ankur raises an interesting point. A gasifier can make char
by removing charcoal faster than you reduce it to gas. We did some
experiments with a 200 kWe Ankur gasifier. During normal operation char
production is about 5% with a  volatile Matter (VM) content of about 10% .
When we ran at a high char withdrawal rate we were making about 10% char
with a VM of 28%.  The point is that if you run a gasifier as a pyrolyzer
then the quality of the char is likely to change.

Hi All,

 

Another company in India that have successful biomass to energy projects
goings for over 20yrs is http://www.ankurscientific.com/whygasification.htm
for a look at feedstock's and solutions take a look at their range
http://www.ankurscientific.com/range.htm . Ankur already have off the shelf
charcoal producing gasifiers suitable for both forest and agricultural
waste. They also have a new anaerobic digestion process for methane
production for details contact gpnagori at ankurscientific.com  . 

 

 

 

Regards,

Rob.
