Abstract
Steve Peterson - Research Chemist at the USDA-ARS in Peoria, IL. Biochar is a very versatile and useful material in many applications beyond carbon sequestration in soils. Rubber composite filler, sorptive media for toxic aqueous components, and peat moss replacement are all examples of biochar applications we have studied at our laboratory. We have two means of producing biochar, the first is by utilizing a top-lit updraft stove, and the second method uses a retort oven under nitrogen to pyrolyze the feedstock into biochar. In this study, we took three different feedstocks (pelletized wheat straw with and without glycerin, and corn stover) and produced biochar using both the TLUD stove (one temperature) and the retort oven (400°, 500°, 600°, and 700°C). These biochar samples were then compared in terms of surface area, density, elemental analysis, and several other physical and chemical characterization methods. Trends in the final biochar properties as a function of the production methods will be discussed in terms of what final properties are desired for each specific end-use application.
