Production of Biochar and Activated Carbon via Intermediate Pyrolysis – Recent Studies for Non‐Woody Biomass

Abstract

Pyrolysis char, a so-called black (dark) earth or biochar, is obtained today usually as a byproduct from charcoal production from wood. Use of biochar in co-combustion or for activated carbon production is a straight forward application; use of biochar in the agricultural environment is a more sensitive approach. The preconditioning of biomass for activated carbon production can realise a so-called biochar in the first stage. Biochar from non-woody biomass therefore needs to be conditioned. Extraction with water is one cheap and applicable solution to realise a liquid fertiliser. Preconditioned biochar from pyrolysis is positioned within the reactor prior to the experiment.
