Carbon nanoballs made from glucose via hydrothermal carbonization, that have been processed with CO2 for 6 hours to change surface properties. SEM image from University of Tartu.
Basics
- Hydrothermal Carbonization (HTC), also known as "hydrochar", is a form of thermal biomass conversion that involves moderate temperatures and pressures over an aqueous solution of biomass in a dilute acid for several hours.
- One advantage of the HTC process over conventional dry-thermal pre-treatments is the ability to handle wet feedstock without pre-drying.
- The resulting "biocoal" can be used as a Fuel or Chemical Feedstock, as a Soil Amendment (similar to biochar), and as a filtration media, among other things
- ’’’As with how Torrefaction is essentially partial Pyrolysis caused by calmer reaction conditions, HTC can be “tuned” to produce Pure Carbon, or something more akin to Lignite
Clarification on Carbon Produced
- ’’’Hydrochar’’’ shall be used as the term for (Near) Pure Amorphous Carbon which is similar to Charcoal , Carbon Black , or Petcoke and can be used as such
- ’’’Bio-Coal’’’ shall be used to refer to Oily Product intended for use as a Solid Fuel akin to Lignite / Bituminous Coal , or as a Chemical Feedstock for products such as Asphaultum (Useful for Japan Black , a durable Metal Coating called Japanning ) , Humic Acids , or potentially Wax akin to Cerasin Wax , Ozokerite , Motan Wax
