  • Patent number: 11111185
    Abstract: Biochar is provided that is treated to have certain chemical and physical properties found to have the highest impact on plant growth and/or soil health. In particular, the following physical and/or chemical properties, among others, of a biochar have been identified as critical properties to control for in the selection of biomass feedstock, pyrolysis conditions, and/or enhancing treatment to increase biochar performance: (i) bulk density (ii) impregnation capacity; (iii) particle size distribution; (iv) solid particle density; (v) surface area; (vi) porosity; (vii) total porosity; (viii) ratio of macroporosity to total porosity (ix) content of residual organic compounds; (x) content of volatile organic compounds; (xii) ash content; (xiii) water holding capacity; (xiv) water retention capabilities; (xv) levels of dioxins and other potentially hazardous byproducts of pyrolysis; and (xvi) pH.

  • Publication number: 20160326067
    Abstract: Treated biochar and methods for treating biochar are provided. The method for treating the biochar includes forcing, assisting or accelerating the movement of an infiltrant into the pores of the biochar, whereby the treatment affects properties of the biochar that provide for a more reliable and predictable biochar for use in various applications, including, but not limited to, agricultural applications.

  • Patent number: 8507004
    Abstract: Systems and methods for use of magnesium hydroxide, either directly or through one or more precursors, doped with a divalent or trivalent metal cation, for removing arsenic from drinking water, including water distribution systems. In one embodiment, magnesium hydroxide, Mg(OH)2 (a strong adsorbent for arsenic) doped with a divalent or trivalent metal cation is used to adsorb arsenic. The complex consisting of arsenic adsorbed on Mg(OH)2 doped with a divalent or trivalent metal cation is subsequently removed from the water by conventional means, including filtration, settling, skimming, vortexing, centrifugation, magnetic separation, or other well-known separation systems. In another embodiment, magnesium oxide, MgO, is employed, which reacts with water to form Mg(OH)2. The resulting Mg(OH)2 doped with a divalent or trivalent metal cation, then adsorbs arsenic, as set forth above. The method can also be used to treat human or animal poisoning with arsenic.
