BIOCHAR FROM THERMAL WITH BENEFICIATED FEEDSTOCK

摘要

A renewable processed biochar composition made with an oxygen-deficient thermal sub-system from a processed organic-carbon-containing feedstock made with a beneficiation sub-system is described. Renewable biomass feedstock passed through a beneficiation sub-system to reduce water content to below at least 20 wt% and water-soluble salt reduction of at least 60 % from that of unprocessed organic-carbon-containing feedstock on a dry basis. The processed feedstock is introduced into an oxygen-deficient thermal sub-system to result in renewable processed biochar having an energy density of at least 17 MMBTU/ton (20 GJ/MT) a water content of less than 10 wt%, and water-soluble salt that is decreased by at least 60 wt% on a dry basis from that of the unprocessed organic-carbon-containing feedstock.
