Abstract
A process for making a biochar composition by passing renewable organic-carbon-containing feedstock through a beneficiation sub-system to reduce water content followed by introducing beneficiated feedstock 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.
Claims14
A process of making processed biochar comprising:
- passing renewable unprocessed organic-carbon-containing feedstock that includes free water, intercellular water, intracellular water, intracellular water-soluble salts, and at least some plant cells comprising cell walls that include lignin, hemicellulose, and microfibrils within fibrils through a beneficiation sub-system to produce processed organic-carbon-containing feedstock having a water content of less than 20 wt % and a salt content that is reduced by at least 60 wt % on a dry basis from that of the unprocessed organic-carbon-containing feedstock;
- and
- passing the processed organic-carbon-containing feedstock an oxygen-deprived thermal sub-system process to produce 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.
A process of making processed biochar comprising:
- inputting unprocessed organic-carbon-containing feedstock into a reaction chamber;
- exposing the feedstock to hot solvent under pressure;
- removing the pressure to for pressed feedstock;
- and
- pressing the pressed feedstock so as to created processed organic-carbon-containing feedstock that has a water content of less than 20% by weight and a water-soluble salt contend that is decreased by at least 60% from that of unprocessed organic-carbon-containing feedstock.
