Abstract

Poultry manure can be completely gasified in supercritical water. In this paper, the behavior of the seven inorganic elements, N, Ca, K, P, S, Cl and Si in layer poutlry manure during supercritical water gasification has been studied to analyze the potential of the by-products of poultry manure gasification for recycling. The inorganic elements in the starting poultry manure, and in the solid and liquid phases after reaction, were quantitatively analyzed. Furthermore, the experimental data were confirmed with thermodynamic equilibrium calculations using computer software. Following gasification the elements N, K and Cl partitioned almost completely into the liquid phase, Ca, P and Si partitioned almost completely into the solid phase, and S partitioned between both phases.
