Rezumat:

During the bituminization process of spent resins, because of the high temperature, a significant amount of gas is produced. Besides water vapours, it contains degradation products of resin and bitumen. The qualitative and quantitative analysis of the condensable gas mixture was made by a tandem technique, GC/MS system. All resulted compounds have been determined: dimethyl- and trimethylamine, n-paraffins (C8-C27), isoparaffins and aromatic hydrocarbons
