ABSTRACT

The present study compares the energetic potential of the gasification gasproduced from the gasification of lignocellulosic wastes (Eucalyptus) and its co-gasification withpolymeric wastes (Refuse-Derivate-Fuel pellets) at an incorporation rate of 30 wt%. The gasification tests were performed using a downdraft reactor, at 800° C,and the gasification gas was collected at equilibrium conditions. The gasification by-products (biochars and tars) were also collected at the end of each test. The results demonstrated that these two types of fuels, may be successfullyconverted producing a syngas with a heating value exceeding 5 MJ/Nm3. The results also demonstrate the advantage of adding polymeric waste to the lignocellulosic biomass, since feeding operations are facilitated by mixing those fuels and the calorific value of the gasification gasincreased by 6% to a final value of 5.4 MJ/Nm3.
