Biochar production from freshwater algae by slow pyrolysis
Abstract
A study on the feasibility of biochar production from 3 kinds of freshwateralgae, viz. Spirulina, Spirogyra and Cladophora, was undertaken. Using a slow pyrolysis process in a specially designed reactor, biochar could be generated at 550oC under nitrogen atmosphere. The yields of biochar were between 28-31% of the dry algae.
