Cultivation of the hazel and almond is widespread in Italy, especially in those small and medium enterprises that work in the confectionery industry. The residual wastes of these productions are mostly shells, of ligno-cellulosic material, very suitable for combustion. The first aim of this work was to carry out the chemical characterization of such wastes (LHV, C, H, N, O, etc) for their energy exploitation. These analyses were performed in the laboratory CIRDER of Viterbo, in accordance with UNI standards. These wastes were then used in a fluidized bed bench scale gasifier to evaluate the composition of the raw gas (H2, CO, CO2, CH4, TAR) obtained during steam gasification tests. The TAR removal efficiencies of two different methods were finally investigated experimentally: catalytic cracking in a secondary reactor with Ni/Al2O3 and scrubbing with vegetable sunflower oil.

Abstract
Cultivation of the hazel and almond is widespread in Italy, especially in those small and medium enterprises that work in the confectionery industry. The residual wastes of these productions are mostly shells, of ligno-cellulosic material, very suitable for combustion. The first aim of this work was to carry out the chemical characterization of such wastes (LHV, C, H, N, O, etc) for their energy exploitation. These analyses were performed in the laboratory CIRDER of Viterbo, in accordance with UNI standards. These wastes were then used in a fluidized bed bench scale gasifier to evaluate the composition of the raw gas (H2, CO, CO2, CH4, TAR) obtained during steam gasification tests. The TAR removal efficiencies of two different methods were finally investigated experimentally: catalytic cracking in a secondary reactor with Ni/Al2O3 and scrubbing with vegetable sunflower oil.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
