Abstract:
In this work, which focuses on the pyrolysis of dairy manure, we evaluate the impacts of operating settings on kinetic behavior, characterize the feed qualities of the manure, and investigate the distribution and composition of the product. The parameters of the feed were ascertained using proximate, ultimate, calorific, and pseudo-component analysis. To comprehend the kinetics of the pyrolysis process, multiple thermogravimetric analysis (TGA) procedures were used. To forecast product yields and composition, a pyrolysis model was used. A large amount of volatiles, carbon, and oxygen were present in the dairy manure, which had a calorific value of 21.28 MJ/kg. Dehydration, component breakdown, and char degradation comprised the three steps of pyrolysis. The kinetic and thermodynamic parameters, as well as the yields of biochar, bio-oil, and syngas, were significantly influenced by the operating conditions. The maximum yields for biochar, bio-oil, and syngas are achieved at 350°C, 550°C, and 850°C, respectively. The biochar contained more carbon than the bio-oil, which contained a variety of organic compounds with possible uses. Techno-economic analysis is recommended to assess the feasibility of pyrolyzing wet biomass. This study provides valuable insights for utilizing dairy manure as an energy source and designing efficient pyrolysis systems for sustainable waste management.
