Abstract:
In this study, co-pyrolysis of wood biomass and waste tyres was carried out in a fixed-bed reactor using different proportions in the feedstock. The aim of this study was to test if an improvement exists on the properties of the condensable liquid fraction (less oxygen and water contents and higher heating value) when co-pyrolysis of these two materials is conducted. The possible synergic effects which can lead to an improve in the properties of the liquid fraction were also investigated. Experiments were carried out in a thermobalance, in a fixed-bed reactor and in an auger reactor pilot plant to test the scalability of the process. Moreover, in order to evaluate the possible use of this fraction as a fuel, liquid properties such as heating value, elemental analysis, pH, Total Acid Number (TAN), density, viscosity and water content were also determined. As expected, the results obtained from fixed bed reactor showed an increase in the heating value of the liquid fraction as the proportion of tyre increases. Thus, Bio60 (containing 60% biomass and 40% tyre in weight basis) and Bio80 (containing 80% biomass and 20% tyre in weight basis) showed a higher heating value of 24.18 and 16.54 MJ/kg respectively, comparing to Bio100 (15.24 MJ/kg). On the other hand results obtained from auger reactor showed major effects in the liquid properties. Heating value was higher and other properties (pH, TAN, oxygen content) were also improved.
