Abstract:
The thermochemical conversion of corncob through fast pyrolysis, follow by catalytic hydrotreatment (HDT) of the fast pyrolysis bio-oil (FPBO), was investigated in this study. The corncob biomass was submitted to the fast pyrolysis treatment at 550 °C with a feeding rate of 10 kg/h for FPBO production. The FPBO underwent catalytic HDT at 250 °C for 50 minutes, using the Pd-Nb catalyst with the goal of reducing the oxygen content of this fraction while improving the overall FPBO properties. The C/O content was 1.23 on the raw corncob 2.11 on the bio-oil and after the HDT treatment, the C/O content increased to 3.17. After the HDT treatment, compounds known to cause FPBO instability, such as aldehydes and carbohydrates were completely converted. Ketones content, on the other hand, was reduced by 54% wt. Therefore, the thermochemical conversion route seems to be a promising alternative for valorization of corn cob, a high lignin content biomass produced in high volumes in emerging countries such as Brazil, with potential to produce renewable fuel if an upgrading step is combined with the fast pyrolysis conversion technology.
