Experimental analysis of waste polyurethane from household appliances and its utilization possibilities

Popis výsledku v původním jazyce

Polyurethane has a good insulation characteristic and a good chemical resistance. Due to these two properties, it represents an excellent insulation and lining material for refrigerators and freezers. Nevertheless, as these appliances are discarded at the end of a lifetime, serious problems arise related to their waste management. Lately, energy recovery has been marked as a most promising solution, especially in the form of waste-to-energy applications. In order to find an appropriate application of such waste, thermal analysis is performed. Experimental analysis of polyurethane (PU) waste material was performed by the method of pyrolysis gas chromatography with mass spectrometric detection (Py-GC/MS) at various pyrolytic temperatures, namely at 500, 600 and 700 oC. Waste polyurethane foam was conducted to investigations in the form of bulk sample and sorted grain size samples with a goal to detect the chemical composition of pyrolysis residue. Investigated samples contain various groups of organic compounds in various concentrations. The most important compounds include heterocyclic compounds of nitrogen, aromatic hydrocarbons, and polycyclic aromatic hydrocarbons, while special attention was given to the formation of harmful compounds containing chlorine and similar. Compounds containing heterocyclic nitrogen, especially amines belong to compounds with the highest concentrations in pyrolysates. The experimental analysis found important differences in the composition of amines and other compounds, in dependence on grain size composition. Bulk samples produce the highest concentration of amines (&gt; 40%) at a temperature of 500 oC. The temperature increment leads to a decrease of amines concentration. On the contrary, the sample homogenization leads to a significant increase of amines production. Polyurethane waste of grain size from 0.125 to 0.25 mm contained 80% more amines. The yield of amines is also influenced by temperature. Temperature increase (over 600 oC) leads to a decrease in amines concentration.
