Pyrolysis process and products

• The production of biochar via pyrolysis also yields bioenergy in the form of syn-gas and bio-oil.
• Maximization of biochar output is at the expense of bioenergy production.

Factors favoring biochar formation vs.
syn-gas and bio-oil formation are:

• Lower temperature
• Slower heating rates
• Longer vapor residence times
• Higher pressure
• Higher feedstock particle size
