High Ammonia Absorbing Corn Stover Hydrochar for use in Horse Bedding
mmonia Absorption in the Gas PhaseA corn stover-based hydrochar material shows superior ammonia sorption ability under ambient temperature and pressure. The hydrochar is produced by processing corn stover and vegetable oil using hydrothermal carbonization. The resulting product is expected to remediate ammonia generation in horse barns and could therefore have valuable applications as horse bedding. The technology also has potential applications in agricultural farming, industrial systems and waste water treatment facilities as well as applications in playgrounds, stadiums and residential lawns.Effective, Low Cost Ammonia AbsorbentA variety of conditions cause nuisance ammonia gas, but there are currently no cost effective solutions to remove it from the air. And while various hydrochars from agricultural residues and fermentation residues are effective, they can be expensive and may require severe treatments, increasing safety and environmental issues. This hydrochar, produced from corn stover and corn oils in distiller grain (or any other vegetable oil source), shows promise as a unique and effective low cost ammonia sorbent. The technology uses condensed distillers solubles, a byproduct of corn ethanol fermentation, and corn stover to produce a char with a much higher capacity to absorb ammonia in the gas phase than hydrochar obtained from agricultural residues.BENEFITS AND FEATURES:Absorbs ammonia in the gas phase at ambient temperature and pressureManufactured using a standard hydrothermal carbonization processIncreases value of low value condensed distillers solublesLow cost sorbent (made from inexpensive and widely available agricultural residues)Does not require strong nitric acid or high temperatures to activate the hydrocharRemediates ammonia generation in horse barns and in other applications such as cat litterCould be used to make a dual purpose agricultural mulch that adds both organic materials and ammonia nitrogen to soilsAPPLICATIONS:Dual use: Ammonia capture from animal waste and then disposed of as ammonia nitrogen source for agricultural useSlow release nitrogen fertilizerHorse bedding and kitty litterAdditive to agricultural fields to reduce gaseous ammonia in the atmospherePrevention of ammonia being released in non-agricultural settings (e.g., kitty litter)Industrial systems and wastewater treatment facilitiesResidential applicationsPlaygrounds and stadiumsPhase of Development - Prototype development
