Revalorización de Residuos Agrícolas por Pirólisis Térmica y Catalítica

Abstract

Thermal and catalytic pyrolysis of peanut shells were performed in a fixed-bed reactor at 500ºC for 20 minutes and with a biomass:catalyst ratio of 1:1, in order to reach this discard revalorization. The catalytic materials tested were Y zeolites in the proton form and with the addition of 3 and 6% of nickel. The effect of the catalysts over the composition and product yields was investigated and the results were compared with the non-catalytic experiments. No qualitative differences were observed in the bio-oils obtained from catalytic and thermal runs. On the contrary, bio-oil yield increased with increasing the proportion of nickel over the zeolite.
