Characteristics of Corn Grains Pyrolysis in a Fixed Bed Reactor

Abstract:

Corn grains pyrolysis was performed in a fixed bed reactor under carbon dioxide atmosphere, producing a char, pyrolytic oil and incondensable gases. The distribution of these fractions was dependent on variations in heat flux, carbon dioxide superficial velocity and grain size. A 23 factorial experiment was employed in order to establish correlations between these factors and process dependent variables, namely char mass, oil mass, operation time, material bed centre temperature, reactor wall temperature and volatiles temperature. A one-stage global reaction kinetic model was selected to describe the process dynamics and its parameters were estimated based on experimental data. The research results may provide useful data to design, scale-up and operate the fixed bed pyrolysis reactors.
