Technical Abstract: Reducing ammonia and hydrogen sulfide emissions from livestock facilities is an important issue for many communities and livestock producers. The emission of these gases can be substantially reduced using adsorption filters filled with biochar produced from pyrolysis of livestock residuals such as chicken litter and swine solid. The objective of this study is to evaluate the performance of biochar adsorption columns. Different biochars are produced from pyrolyzing various animal manures. Chicken litter, swine solids, and mixture of swine solids and hays will be pyrolyzed in a small high temperature bench reactor system. The feedstock will be heated to 250 degrees Celsius and 500 degrees Celsius without oxygen. The feedstock and the biochar will be characterized with proximate and ultimate analyses. Adsorption characteristics of these biochars will be tested with column tests using calibrated gases and photoacoustic multi-gas analyzer.
