Transformation of inorganic matter in poultry litter during fluidised bed gasification

This work investigates the transformation, release and fate of inorganic matter during fluidised bed gasification poultry litter also mixed with limestone as an additive. The litter, cyclone ash were characterised by means chemical fractionation analysis, well X-ray diffraction. Concurrently, species feedstock was measured in separate laboratory experiments using molecular beam mass spectrometry. In addition, FactSage used to predict formation gaseous composition solid residues from under equilibrium conditions. On average, accounts for 4.6 wt% 12.4 total fed into reactor. All phosphorous (P) present stable phosphates, while potassium (K) both mainly H2O leachable KCl, organically associated phosphates silicates. Furthermore, assessment made against appropriate criteria, whether ashes can be categorised component materials EU fertiliser products.
