Abstract
Se realizaron pirolisis térmicas y catalíticas de cáscaras de maní en un reactor de lecho fijo a
500ºC y durante 20 minutos, con una relación biomasa:catalizador de 1:1, en pos de lograr la
revalorización del desecho. Los materiales catalíticos evaluados fueron zeolitas Y en forma
protónica y con 3 y 6% de níquel incorporado a la misma. Se estudió el efecto de los catalizadores
sobre la composición y el rendimiento de los productos de reacción y los resultados se
compararon con las corridas netamente térmicas. No se observaron diferencias cualitativas entre
los bio-oils de las experiencias térmicas y catalíticas. En contraposición, el rendimiento del líquido
aumentó al aumentar la proporción de níquel en el catalizador.
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.
