Technical Abstract: Malodorous emissions from livestock operations disrupt quality of life in rural and urban communities. The objective of this study is to characterize various biochars, both made from wet and dry pyrolysis of biomass, in terms of their potential capacity to be used as a sorbent for removing odorous compounds typically found in animal manures. Pine, oak, swine manure, and poultry litter were selected as potential biomass feedstocks. Pellets of each of these biomass feedstocks were pyrolyzed at 350 degrees Celsius and 500 degree Celsius using a Lindburg electric box furnace equipped with a gas tight retort (Model 51662; Lindburg/MPH, Riverside, MI). Some of these were also partially activated with steam at 700 degrees Celsius. In addition, swine hydrochars were prepared by hydrothermally carbonizing swine solids at 250 degrees Celsius and its autogenic pressures. The biochar/hydrochar samples were then analyzed for their chemical elemental compositions, volatile matter, fixed carbon, ash contents, density, and surface areas. Sorption capacities of ammonia, one of odorous compounds from animal manures, will be determined using these biochars/hydrochars as sorbents. These results will be presented at the meeting.
