Abstract
A method and system of converting biomass to biochar in a hydrothermal carbonization apparatus wherein subcritical water at a temperature of 230-350° C. and 500-3000 psi is reacted with the biomass to form biochar, biocrude and gases. The method and system include recycling the biocrude back to the hydrothermal carbonization apparatus which improves biochar yield and provides water for the biomass reaction to occur.
