Oxygen-Deficient Thermally Produced Processed Biochar from Beneficiated Organic-Carbon-Containing 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.

1. A composition, comprising:
a processed biochar composition that comprises a solid renewable carbon fuel with characteristics that include an energy density of at least 17 MMBTU/ton (20 GJ/MT), a water content of less than 10 wt %, and a water-soluble salt content that is decreased more than 60 wt % on a dry basis from that of unprocessed organic-carbon-containing feedstock, and the processed biochar is made from unprocessed organic-carbon-containing feedstock that is converted into the processed organic-carbon-containing feedstock with a beneficiation sub-system, and to the processed biochar with an oxygen-deficient thermal sub-system.
